On May 31, 2022, Elloumi, Nesrine; Tahri, Safa; Fakhfakh, Raouia; Abida, Olfa; Mahfoudh, Nadia; Hachicha, Hend; Marzouk, Sameh; Bahloul, Zouhir; Masmoudi, Hatem published an article.Recommanded Product: 5-Methylpyrimidine-2,4(1H,3H)-dione The title of the article was Role of innate immune receptors TLR4 and TLR2 polymorphisms in systemic lupus erythematosus susceptibility. And the article contained the following:

Through their recognition of various bacterial cell wall components, TLR2 and TLR4 participate in the innate response and modulate the activation of adaptive immunity. Therefore, the genetic background of these receptors might play a crucial role in autoimmune diseases such as systemic lupus erythematosus (SLE). In this study, we investigated the possible association between polymorphisms within TLR2 and TLR4 genes with SLE susceptibility. A total of 100 SLE patients and 200 unrelated healthy controls of the Tunisian population were enrolled in the study. TLR4rs4986790, TLR4rs4986791, and TLR2rs5743708 genotyping were performed using a polymerase chain reaction-restriction fragment length polymorphism method. The number of guanine-thymine (GT) repeat microsatellite in the intron 2 of TLR2 gene was analyzed by sequencing. We reported a lack of allelic and genotypic association between SNPs of TLR4 and TLR2 genes and SLE pathogenesis. No correlation was found with any SLE features. However, SLE susceptibility was associated with the GT repeat microsatellite polymorphism in the human TLR2 gene. Further subclassification of alleles into three subclasses revealed a significant association between the long-sized repeats ((GT) >23) and SLE. Though the results showed the absence of genetic association of TLR4 and TLR2 SNPs with the risk of developing SLE, we have identified a protective association between the microsatellite polymorphism in intron 2 of the TLR2 gene and SLE. Functionally, these (GT)n repeats may confer modifying effects or susceptibility to certain inflammatory conditions. The experimental process involved the reaction of 5-Methylpyrimidine-2,4(1H,3H)-dione(cas: 65-71-4).Recommanded Product: 5-Methylpyrimidine-2,4(1H,3H)-dione

And the article contained the following:

Our multicenter phase II TAS-CC3 study demonstrated favorable median progression-free survival (PFS) and overall survival (OS) of 32 metastatic colorectal cancer (mCRC) patients treated with TAS-102 + bevacizumab as 3rd-line treatment. We investigated the predictive and prognostic values of pre-treatment blood inflammation-based scores, including the neutrophil-to-lymphocyte (NLR), platelet-to-lymphocyte (PLR) and lymphocyte-to-monocyte ratio (LMR) on disease-control (DC), PFS and OS by a post-hoc anal. Receiver operating characteristic curve analyses of the 3 inflammation-based scores vs. DC showed the best predictive performance for LMR, followed by NLR and PLR. The high-LMR group had a significantly higher DC rate than the low group (87.5 vs. 43.8%). The high-LMR group showed significantly longer survival than the low group (4.9 vs. 2.3 m for median PFS) (21.0 vs. 6.1 m for median OS). The pre-treatment LMR is a valid predictive and prognostic biomarker for mCRC patients undergoing TAS-102 and bevacizumab treatment.

And the article contained the following:

Trifluridine (FTD) is the active component of the nucleoside chemotherapeutic drug trifluridine/tipiracil (FTD/TPI), which is approved worldwide for the treatment of patients with metastatic gastrointestinal cancer. FTD exerts cytotoxic effects via its incorporation into DNA, but FTD has not been detected in the tumor specimens of patients. The purpose of this study was to detect FTD in tumors resected from metastatic colorectal cancer (mCRC) patients who were administered FTD/TPI. Another purpose was to investigate the turnover rate of FTD in tumors and bone marrow in a mouse model. Tumors and normal tissue specimens were obtained from mCRC patients who were administered FTD/TPI or placebo at Kyushu University Hospital. Tumors and bone marrow were resected from mice with peritoneal dissemination treated with FTD/TPI. To detect and quantitate FTD incorporated into DNA, immunohistochem. staining of paraffin-embedded specimens (IHC-p staining) and slot-blot anal. of DNA purified from these tissues were performed using an anti-BrdU antibody. IHC-p staining of proliferation and apoptosis markers was also performed. FTD was detected in metastatic tumors obtained from mCRC patients who were administered FTD/TPI, but who had discontinued the treatment several weeks before surgery. In a peritoneal dissemination mouse model, FTD was still detected in tumors 13 days after the cessation of FTD/TPI treatment, but had disappeared from bone marrow within 6 days. These results indicate that FTD persists longer in tumors than in bone marrow, which may cause a sustained antitumor effect with tolerable hematotoxicity.

Preliminary studies of FTD/TPI plus bevacizumab have produced encouraging results in the treatment of refractory metastatic colorectal cancer. Here, we describe the design of the multinational Phase III SUNLIGHT, an open-label study of FTD/TPI plus bevacizumab as third-line treatment for patients with unresectable metastatic colorectal cancer. A total of 490 patients will be randomized 1:1 to receive either FTD/TPI plus bevacizumab, or FTD/TPI monotherapy. The primary objective is to significantly improve overall survival with FTD/TPI plus bevacizumab compared with FTD/TPI monotherapy. The first patient was enrolled in Nov. 2020. Lay abstract : Trifluridine/tipiracil is a cancer treatment used in patients with bowel cancer that has spread to other parts of the body (this is called ‘metastatic bowel cancer’). This medicine is taken by mouth. Recently, a number of studies have suggested that better results might be obtained when trifluridine/tipiracil is used in combination with another cancer drug, bevacizumab. This article describes the design of a new clin. trial. The SUNLIGHT is being set up to confirm whether the combination of trifluridine/tipiracil plus bevacizumab is indeed better than trifluridine/tipiracil alone for patients who have already had two different treatments for metastatic bowel cancer. The trial began in late 2020. The experimental process involved the reaction of 5-Methylpyrimidine-2,4(1H,3H)-dione(cas: 65-71-4).Related Products of 65-71-4

And the article contained the following:

A review. Congenital hydrocephalus (CH) is caused by genetic mutations, but whether factors impacting human genetic mutations are disease-specific remains elusive. Given two factors associated with high mutation rates, we reviewed how many disease-susceptible genes match with (i) proximity to telomeres or (ii) high adenine and thymine (A + T) content in human CH as compared to other disorders of the central nervous system (CNS). We extracted genomic information using a genome data viewer. Importantly, 98 of 108 genes causing CH satisfied (i) or (ii), resulting in >90% matching rate. However, such a high accordance no longer sustained as we checked two factors in Alzheimers disease (AD) and/or familial Parkinsons disease (fPD), resulting in 84% and 59% matching, resp. A disease-specific matching of telomere proximity or high A + T content predicts causative genes of CH much better than neurodegenerative diseases and other CNS conditions, likely due to sufficient number of known causative genes (n = 108) and precise determination and classification of the genotype and phenotype. Our anal. suggests a need for identifying genetic basis of both factors before human clin. studies, to prioritize putative genes found in preclin. models into the likely (meeting at least one) and more likely candidate (meeting both), which predisposes human genes to mutations.

And the article contained the following:

This study assessed the efficacy and safety of biweekly trifluridine and tipiracil hydrochloride (TAS-102) with bevacizumab combination therapy for patients with metastatic colorectal cancer (mCRC). We included 19 patients with mCRC who received TAS-102 and bevacizumab combination therapy biweekly as third-line chemotherapy. The primary endpoint was progression-free survival. Patients had a median age of 73 years and most (73.4%) were men. The median progression-free and overall survival were 5.6 and 11.5 mo, resp. Five (26.3%) patients achieved a response and the disease control rate was 12/19 (63.1%). One patient (5.2%) experienced neutropenia grade 3 or more. The median time from baseline performance status 0/1 to worsening to 2 or more was 10.3 mo. Biweekly TAS-102 plus bevacizumab facilitates tumor shrinkage by reducing the incidence of grade 3 or more neutropenia, improving survival, and maintaining performance status. This combination may represent a treatment option for patients with late-stage rnCRC receiving third- or later-line therapy.

Molecular Docking and Three-Dimensional Quantitative Structure-Activity Relationships for Antitubercular Pyrimidine Derivatives

Enoyl Acyl Carrier Protein (ACP) Reductase, a key enzyme, which catalyzes the last reductive step of fatty acid biosynthesis and it, is one of the key enzymes for the development of antitubercular agents. In this pursuit, molecular docking and 3D-QSAR studies (CoMFA and CoMSIA) have been performed on a series of pyrimidine derivatives (29 compounds) to understand the binding sites, interactions to improve over the existing leads in terms of improved biological and physico-chemical properties. Molecular docking was performed on a protein InhA (T2A mutant) (PDB ID: 5OIR) using the Surflex-Dock suite available in SYBYL-X 2.1.1 (Tripose Inc., USA). In addition, 3D-QSAR studies have been performed to validate the models using the data set, which was segregated into training and test set by using the Diversity and Dissimilarity method. Structural features required for the prediction of better inhibitory potency was generated in the form of contour maps from the CoMFA and CoMSIA models (Steric, Electrostatic, Hydrophobicity, H-bond donor and acceptor maps) and predicted values for r(2) = 0.966, q(2) = 0.22 for the CoMFA model and r(2) = 0.925, q(2) = 0.576 for the CoMSIA model. From this study, it is observed that interaction with amino acid residues TYR158, MET199, MET161, GLY96, and PHE97 are important for the activity that helped to predict SARs by providing important structural features. Both the models were good in understanding the specific activity of some of the compounds that will facilitate to develop new types of Enoyl ACP reductase inhibitors.

Intrauterine Inflammation Alters the Transcriptome and Metabolome in Placenta

Placental insufficiency is implicated in spontaneous preterm birth (SPTB) associated with intrauterine inflammation. We hypothesized that intrauterine inflammation leads to deficits in the capacity of the placenta to maintain bioenergetic and metabolic stability during pregnancy ultimately resulting in SPTB. Using a mouse model of intrauterine inflammation that leads to preterm delivery, we performed RNA-seq and metabolomics studies to assess how intrauterine inflammation alters gene expression and/or modulates metabolite production and abundance in the placenta. 1871 differentially expressed genes were identified in LPS-exposed placenta. Among them, 1,149 and 722 transcripts were increased and decreased, respectively. Ingenuity pathway analysis showed alterations in genes and canonical pathways critical for regulating oxidative stress, mitochondrial function, metabolisms of glucose and lipids, and vascular reactivity in LPS-exposed placenta. Many upstream regulators and master regulators important for nutrient-sensing and mitochondrial function were also altered in inflammation exposed placentae, including STAT1, HIF1 alpha, mTOR, AMPK, and PPAR alpha. Comprehensive quantification of metabolites demonstrated significant alterations in the glucose utilization, metabolisms of branched-chain amino acids, lipids, purine and pyrimidine, as well as carbon flow in TCA cycle in LPS-exposed placenta compared to control placenta. The transcriptome and metabolome were also integrated to assess the interactions of altered genes and metabolites. Collectively, significant and biologically relevant alterations in the placenta transcriptome and metabolome were identified in placentae exposed to intrauterine inflammation. Altered mitochondrial function and energy metabolism may underline the mechanisms of inflammation-induced placental dysfunction.

Comparative study between the anti-P. falciparum activity of triazolopyrimidine, pyrazolopyrimidine and quinoline derivatives and the identification of new PfDHODH inhibitors

In this work, we designed and synthesized 35 new triazolopyrimidine, pyrazolopyrimidine and quinoline derivatives as P. falciparum inhibitors (3D7 strain). Thirty compounds exhibited anti-P. falciparum activity, with IC50 values ranging from 0.030 to 9.1 mu M. The [1,2,4] triazolo[1,5-a]pyrimidine derivatives were more potent than the pyrazolo[1,5-a]pyrimidine and quinoline analogues. Compounds 20, 21, 23 and 24 were the most potent inhibitors, with IC50 values in the range of 0.030-0.086 mu M and were equipotent to chloroquine. In addition, the compounds were selective, showing no cytotoxic activity against the human hepatoma cell line HepG2. All [1,2,4]triazolo[1,5-a]pyrimidine derivatives inhibited PfDHODH activity in the low micromolar to low nanomolar range (IC50 values of 0.08-1.3 mu M) and did not show significant inhibition against the HsDHODH homologue (0-30% at 50 mu M). Molecular docking studies indicated the binding mode of [1,2,4]triazolo[1,5-a]pyrimidine derivatives to PfDHODH, and the highest interaction affinities for the PfDHODH enzyme were in agreement with the in vitro experimental evaluation. Thus, the most active compounds against P. falciparum parasites 20 (R = CF3, R-1 = F; IC50 = 0.086 mu M), 21 (R = CF3; R-1 = CH3; IC50 = 0.032 mu M), 23, (R = CF3, R-1 = CF3; IC50 = 0.030 mu M) and 24 (R = CF3, 2-naphthyl; IC50 = 0.050 mu M) and the most active inhibitor against PfDHODH 19 (R = CF3, R-1 = Cl; IC50 = 0.08 mu M – PfDHODH) stood out as new lead compounds for antimalarial drug discovery. Their potent in vitro activity against P. falciparum and the selective inhibition of the PfDHODH enzyme strongly suggest that this is the mechanism of action underlying this series of new [1,2,4]triazolo[1,5-a]pyrimidine derivatives.
