Synthesis of 1-Benzyl-3-(5‘-hydroxymethyl-2‘-furyl)indazole Analogues as Novel Antiplatelet Agents
摘要:
1-Benzyl-3-(5'-hydroxymethyl-2'-furyl)indazole (28, YC-1) was selected as the lead compound for systemic structural modification. After screening for antiplatelet activity, SARs of YC-1 analogues were established. Among these potent active derivatives, compounds 29, 30, 31, 44, and 45 functioned as potent activators of sGC and inhibitors of PDE5 with potency comparable to that of YC-1. In addition, compound 58 was found to be a selective and potent inhibitor of protease-activated receptor type 4 (PAR4)-dependent platelet activation.
1-Benzyl-3-(5‘-hydroxymethyl-2‘-furyl)indazole (YC-1) Derivatives as Novel Inhibitors Against Sodium Nitroprusside-Induced Apoptosis
摘要:
Antiapoptotic agents based on 1-benzyl-3-(5'-hydroxymethyl-2'-furyl)indazole (22, YC-1) derivatives were explored for effective treatment of sepsis and septic shock. We found that compound 22, 1-benzyl-3-(5'-methoxymethyl-2'-furyl)indazole (27), and 1-phenyl-3-(5'-hydroxymethyl-2'-furyl)-indazole (23) were the most effective inhibitors of sodium nitroprusside-induced vascular smooth muscle cell apoptosis. These three compounds are proposed as potential therapeutic agents for the treatment of sepsis.
