Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. Formula: C10H7ClN2. Introducing a new discovery about 20375-65-9, Name is 3-Phenyl-6-chloropyridazine

Carboxylic acid bioisosteres of gamma-linked dipeptide analogues of the folate-based thymidylate synthase (TS) inhibitor, 2-desamino-2-methyl-N10-propargyl-5,8-dideazafolic acid (ICI 198583)

Tetrazole carboxylic acid bioisosteres of gamma-linked dipeptide derivatives of 2-desamino-2-methyl-N10-propargyl-5,8-dideazafolic acid (ICI 198583), a folate-based inhibitor of thymidylate synthase (TS), were synthesised by multistep routes starting from the appropriate pteroic acid analogue and Z-D-Ala or D-Glu. They exhibited excellent TS inhibitory activities which, however, were not accompanied by a parallel improvement in the L1210 cell growth inhibition.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Formula: C10H7ClN2, you can also check out more blogs about20375-65-9

Substituted hippurates and hippurate analogs as substrates and inhibitors of peptidylglycine alpha-hydroxylating monooxygenase (PHM)

Peptidyl alpha-hydroxylating monooxygenase (PHM) functions in vivo towards the biosynthesis of alpha-amidated peptide hormones in mammals and insects. PHM is a potential target for the development of inhibitors as drugs for the treatment of human disease and as insecticides for the management of insect pests. We show here that relatively simple ground state analogs of the PHM substrate hippuric acid (C6H5-CO-NH-CH2-COOH) inhibit the enzyme with Ki values as low as 0.5 muM. Substitution of sulfur atom(s) into the hippuric acid analog increases the affinity of PHM for the inhibitor. Replacement of the acetylglycine moiety, -CO-NH-CH2-COOH with an S-(thioacetyl)thioglycolic acid moiety, -CS-S-CH2-COOH, yields compounds with the highest PHM affinity. Both S-(2-phenylthioacetyl)thioglycolate and S-(4-ethylthiobenzoyl)thioglycolic acid inhibit the proliferation of cultured human prostate cancer cells at concentrations >100-fold excess of their respective Ki values. Comparison of Ki values between mammalian PHM and insect PHM shows differences in potency suggesting that a PHM-based insecticide with limited human toxicity can be developed.

Copper-Catalyzed Diamination of Oxime Ester-Tethered Unactivated Alkenes with Unprotected Amines

In this protocol, a redox-neutral Cu-catalyzed two-component vicinal diamination of oxime ester-tethered unactivated alkenes has been developed. This operationally simple method employs unprotected amines as the source of nucleophilic nitrogen and requires no additional ligand, enabling the efficient synthesis of diverse pyrrolines under mild and oxidant-free conditions. On the basis of the control experiments, a radical reaction pathway was proposed for this Cu-catalyzed reaction.
