Berhane, Ilyas published the artcileThieno[2,3-d]pyrimidine-Based Positive Allosteric Modulators of Human Mas-Related G Protein-Coupled Receptor X1 (MRGPRX1), Application In Synthesis of 439692-55-4, the main research area is MRGPRX1 pos allosteric modulator neuropathic pain analgesic.

Mas-related G protein-coupled receptor X1 (MRGPRX1) is a human sensory neuron-specific receptor and potential target for the treatment of pain. Pos. allosteric modulators (PAMs) of MRGPRX1 have the potential to preferentially activate the receptors at the central terminals of primary sensory neurons and minimize itch side effects caused by peripheral activation. Using a high-throughput screening (HTS) hit, a series of thieno[2,3-d]pyrimidine-based mols. were synthesized and evaluated as human MRGPRX1 PAMs in HEK293 cells stably transfected with human MrgprX1 gene. An iterative process to improve potency and metabolic stability led to the discovery of orally available 6-(tert-butyl)-5-(3,4-dichlorophenyl)-4-(2-(trifluoromethoxy)phenoxy)thieno[2,3-d]pyrimidine (1t), which can be distributed to the spinal cord, the presumed site of action, following oral administration. In a neuropathic pain model induced by sciatic nerve chronic constriction injury (CCI), compound 1t (100 mg/kg, po) reduced behavioral heat hypersensitivity in humanized MRGPRX1 mice, demonstrating the therapeutic potential of MRGPRX1 PAMs in treating neuropathic pain.

Horiuchi, Takao published the artcileDiscovery of novel thieno[2,3-d]pyrimidin-4-yl hydrazone-based inhibitors of Cyclin D1-CDK4: Synthesis, biological evaluation and structure-activity relationships. Part 2, Recommanded Product: Thieno[2,3-d]pyrimidine, 4-chloro-6-(1,1-dimethylethyl)-, the main research area is cyclin dependent kinase 4 CDK4 inhibitor cancer; hydrazone derivative SAR preparation.

The design, synthesis and evaluation of novel thieno[2,3-d]pyrimidin-4-yl hydrazone analogs as cyclin-dependent kinase 4 (CDK4) inhibitor are described. Focusing on the optimization of the heteroaryl moiety at the hydrazone with substituted Ph groups, 4-[(methylamino)methyl]benzaldehyde (22)(I) and 5-isoindolinecarbaldehyde (24)(II) (6-tert-butylthieno[2,3-d]pyrimidin-4-yl)hydrazone derivatives have been identified. In this paper, the potency, selectivity profile and structure-activity relationships of our synthetic compounds are discussed.

Li, Yanjun published the artcileOrganophotocatalytic selective deuterodehalogenation of aryl or alkyl chlorides, Application In Synthesis of 439692-55-4, the main research area is deuterated aryl heteroaryl compound green preparation; aryl chloride alkyl organophotocatalyst selective deuterodehalogenation.

A photocatalytic system consisting of an aryl-amine photocatalyst and a disulfide co-catalyst in the presence of sodium formate as an electron and hydrogen donor was developed. Accordingly, many aryl chlorides, alkyl chlorides, and other halides were converted to deuterated products at room temperature in air (>90 examples, up to 99% D-incorporation). The mechanistic studies revealed that the aryl amine served as reducing photoredox catalyst to initiate cleavage of the C-Cl bond, at the same time as energy transfer catalyst to induce homolysis of the disulfide for consequent deuterium transfer process. This economic and environmentally-friendly method could be used for site-selective D-labeling of a number of bioactive mols. and direct H/D exchange of some drug mols.
