Tetrahydro-isoquinoline-Based Factor Xa Inhibitors
摘要:
Derivatives of (2-amidino-1,2,3,4-tetrahydro-isoquinolin-7-yloxy)phenylacetic acid (TIPAC) were developed as inhibitors of factor Xa (fXa). The compounds are prepared using 15 synthetic steps on average. The most potent compounds (14, 17, 22-26) display inhibition constants of K-i = 21-55 nM but do not inhibit thrombin (K-i = 5->100 mu M) and only weakly inhibit trypsin (K-i = 0.08-5 mu M). They bear a second basic moiety, e.g., substituted 1-(iminomethyl)piperidines, which is linked to C-4 of the phenyl group of TIPAC via an oxygen atom. The inhibition constants of these compounds are almost independent of the size of the (iminomethyl)piperidine substituent. Due to the fact that fXa displays two cation binding sites, namely, the S1 and S4 sites, in principle two binding modes are conceivable for the novel dibasic fXa inhibitors. Molecular modeling experiments based on the X-ray structures of uninhibited fXa and the DX-9065a/fXa complex were carried out. The results taken together with the inhibition constants clearly favor one binding mode: the tetrahydro-isoquinoline fills the S1 pocket even better than the naphthalene moiety of DX-9065a, and the (iminomethyl)piperidine residues occupy the S4 site.

Penem derivatives represented by the following Formula (I):
wherein Z represents a hydroxyl group or a fluorine atom, R1 represents a substituted or unsubstituted alkyl, alkenyl, aralkyl group, aryl group, heterocyclic, or acyl group, or a hydrogen atom, and R2 represents a hydrogen atom or a carboxyl-protecting group; and pharmacologically acceptable salts thereof are antibacterial agents effective against, inter alia, methicillin-resistant Staphylococcus aureus. The derivatives and salts are novel except when R1 is ethyl and Z is hydroxyl. The analogous compounds in which R2 is a carboxyl-protecting group and any hydroxyl group represented by Z is protected are novel process intermediates.
We searched for a strong and selective nonprostanoid IP agonist bearing piperidine and benzanilide moieties. Through optimization of substituents on the benzanilide moiety, the crucial part of the agonist, 43 (2-((1-(2-(N-(4-tolyl)benzo[d][1,3]dioxole-5-carboxamido)ethyl)piperidin-4-yl)oxy)acetic acid monohydrate monohydrochloride) was discovered and exhibited strong platelet aggregation inhibition
