Synthetic adermin was assayed by its influence on growth and acid formation by Streptobact. plantarum (C. A. 32, 9165.1); curves of growth (turbidity) and acidity vs. time are given. The synthetic preparation is slightly more active than the vitamin preparation made from rice hulls. A growth effect upon Streptobact. plantarum is likewise exhibited by 2,4-dimethyl-3-hydroxy-5-(hydroxymethyl)pyridine (hydrochloride m. 254°) although in 50-fold dose the result was only 30-40% of that of the B6 hydrochloride.

Ehrlich ascites, Krebs 2 ascites carcinomas, and sarcoma 180 ascites tumor were used in the present study. Fresh ascites fluid containing 106 cancer cells were injected into mice and the recipient regularly developed large amounts of milky ascites (5 to 20 cc.) in 1 to 2 wk and died in 1 to 3 wk. The tumors had 100% takes and there were generally no spontaneous regressions. The exudates contained 5 to 10% normal cells. For the chemotherapy test, a donor mouse was selected 1 to 2 wk, after inoculation and 2 to 5 mL. of milky fluid withdrawn, the cells counted in a hemocytometer, and a proper dilution made with 0.9% NaCl solution I.p. injections of 0.1 mL. of fluid containing 106 cells was made. Each group of animals was divided into a control and treatment group. The progress of the tumors was recorded by daily weight measurement and by measuring the amount of ascitic fluid 10 days after the inoculation. The inhibition effect was then estimated from the effects on the ascites and the survival. Chemotherapeutic agents were injected in solvents as necessary; 0.5 cc. CM-cellulose, 0.5 cc. peanut oil, 0.1 cc. sesame oil were used. One hundred compounds were tested on all 3 tumors; these consisted of nitrogen mustards, ethyleneimines, phosphoramides, folic acid analogs and other pteridines, carbamates, purines, pyrimidines, formamides, steroids, hormones, enzymes, antibiotics, antivitamins, inorganic salts, and others. In 64% of the tests the response to agents was identical in all 3 tumors. A similar study was made of 54 agents on the solid and ascites form of the Ehrlich carcinoma and sarcoma 180. The ascites form usually showed the greater sensitivity to the carcinostatic agent.

Author is Wikoff, William R.; Nagle, Megha A.; Kouznetsova, Valentina L.; Tsigelny, Igor F.; Nigam, Sanjay K..

Untargeted metabolomics on the plasma and urine from wild-type and organic anion transporter-1 (Oat1/Slc22a6) knockout mice identified a number of physiol. important metabolites, including several not previously linked to Oat1-mediated transport. Several, such as indoxyl sulfate, derive from Phase II metabolism of enteric gut precursors and accumulate in chronic kidney disease (CKD). Other compounds included vitamins (pantothenic acid, 4-pyridoxic acid), urate, and metabolites in the tryptophan and nucleoside pathways. Three metabolites, indoxyl sulfate, kynurenine, and xanthurenic acid, were elevated in the plasma and interacted strongly and directly with Oat1 in vitro with IC50 of 18, 12, and 50 μM, resp. A pharmacophore model based on several identified Oat1 substrates was used to screen the NCI database and candidate compounds interacting with Oat1 were validated in an in vitro assay. Together, the data suggest a complex, previously unidentified remote communication between the gut microbiome, Phase II metabolism in the liver, and elimination via Oats of the kidney, as well as indicating the importance of Oat1 in the handling of endogenous toxins associated with renal failure and uremia. The possibility that some of the compounds identified may be part of a larger remote sensing and signaling pathway is also discussed.

Mesoporous materials (MMs) have recently been applied as advanced nanomaterials in different fields (separation, catalysis, adsorption etc.). Synthesis of MMs by chem. surfactants is not ecofriendly. This study focused on the biol. synthesis of a MM by sol-gel method, using a Bacillus subtilis BBK006-mediated surfactant (template) and a precursor (TEOS). The biol. synthesized mesoporous silica nanoparticles (BMSN) were formed at calcination temperatures of 450-600 °C. The BMSN comprise Si and O elements with sp. weights of 56.09% and 42.13% resp., where the at.% was detected to be 41.79% and 55.10%, resp. The phase identity of the synthesized particles (61-300 nm uniform spherical shape; surface area: 8.2616 m2 g-1; pore diameter at 550 °C: 14.8516 nm) was confirmed with wide-angle XRD (10°-81°). A typical type IV isotherm was exhibited (BET curves) following IUPAC nomenclature and confirmed the mesoporous nature. The green-synthesized biosurfactant-mediated BMSN is an environmentally promising material to apply in biomedical science (e.g., antimicrobial activity, drug delivery, CMC, anticancer activity) and oil spill management.
