N2-Aroylanthranilamide Inhibitors of Human Factor Xa
摘要:
Reversal of the A-ring amide link in 1,2-dibenzamidobenzene 1 (fXa K-ass = 0.81 x 10(6) L/mol) led to a series of human factor Xa (hfXa) inhibitors based on N-2-aroylanthranilamide 4. Expansion of the SAR around 4 showed that only small planar substituents could be accommodated in the A-ring for binding to the S1 site of hfXa. Bulky groups such as 4-isopropyl, 4-tert-butyl, and C-dimethylamino were favored in the B-ring to interact with the S4 site of hfXa. The central (C) ring containing a 5-methanesulfonamido group yielded greater activity than carbamoyl groups. Combining the beneficial features from the B- and C-ring SAR, compound 55 represents the most potent hfXa inhibitor in the N-2-aroylanthranilamide 4 series with hfXa K-ass = 58 x 10(6) L/mol (K-i = 11.5 nM).

A highly effective silver(I)‐mediated CHamination of 2‐alkenylanilines has been developed to afford a diverse range of substituted indoles. High functional group tolerance, broad substrate scope, simple/fast/high‐yielding reaction, and recovery/reuse of the inexpensive silver oxidant are noteworthy. Furthermore, an uncommon migratory process of β‐monosubstituted 2‐alkenylanilines with solvent‐dependence

The present invention relates to a method of making asymmetrical bis(thiosemicarbazones), compounds useful as synthetic intermediates in the method, new bis(thiosemicarbazones) that can be readily accessed by use of the method and methods of treatment and imaging utilising some of the new bis(thiosemicarbazones).
4-naphthoquinone derivatives, and benzo[b]acridine-6,11-diones were formed in good yields. A method has been developed for the synthesis of highly functionalized quinolines from readily available N-(2-alkenylaryl)-substituted enamines via a 6-exo-trig radicalcyclization of an imine radical. Several useful functional groups including morpholinocarbonyl, benzoyl, and cyano, are compatible with the reaction conditions
