Synthesis and biological evaluation of nitric oxide releasing derivatives of 6-amino-3-n-butylphthalide as potential antiplatelet agents
摘要:
A series of novel nitric oxide releasing derivatives of 6-amino-3-n-butylphthalide were designed, synthesized and evaluated as potential antiplatelet agents. Compound 10b significantly inhibited the adenosine diphosphate (ADP)-induced platelet aggregation in vitro, superior to 6-amino-3-n-butylphthalide, 3-n-butylphthalide (NBP) and ticlopidine. Meanwhile 10b released moderate levels of NO, which could be beneficial for improving cardiovascular and cerebral circulation. Furthermore, 10b had an enhanced aqueous solubility relative to NBP. These findings may provide new insights into the development of novel antiplatelet agents for the treatment of thrombosis-related ischemic stroke. (C) 2013 Elsevier Ltd. All rights reserved.

A one-pot efficient, practical and eco-friendly synthesis of tocopherol analogues has been developed using water or solvent free conditions via Passerini and Ugi multicomponent reactions. These reactions can be optimized using microwave irradiation or ultrasound as the energy source. Accordingly, a small library of 30 compounds was prepared for biological tests. The evaluation of the antiproliferative
A series of (nitrooxyacyloxy)methyl esters of aspirin were synthesized and evaluated as new NO-donor aspirins. Different amounts of aspirin were released in serum from these products according to the nature of nitrooxyacyloxy moiety present, In the aromatic series, there is a rather good linear correlation between the amount of aspirin released and the potencies of the products in inhibiting platelet aggregation induced by collagen. Both the native compounds and the related nitrooxy-substituted acid metabolites were able to relax rat aorta strips precontracted with phenylephrine, in keeping with a NO-induced activation or the sGC as a mechanism that underlies the vasodilator effect. The products here described are new improved examples of NO-donor aspirins containing nitrooxy groups. They could represent all alternative to the use of aspirin ill a variety of clinical applications.
