The novel codrugs of Leonurine and Aspirin, compounds 545 and 503 have been synthesized and evaluated on their cardioprotective effects. Preliminary pharmacological studies showed that both compounds 545 and 503 were able to increase cell viability of hypoxia-induced H9c2 cells, and compound 545 exhibited at least ten fold potency than 503 and their parent drugs (Leonurine and Aspirin). Further mechanisms
合成了Leururine和Aspirin的新型前药化合物545和503,并对其心脏保护作用进行了评估。初步的药理研究表明,化合物545和503均能增加缺氧诱导的H9c2细胞的细胞活力,并且化合物545的功效至少比503及其母体药物(利尿氨酸和阿司匹林)高十倍。进一步的机制研究表明545的心脏保护作用是由于其(1)通过增加SOD和CAT酶的活性以及降低MDA含量和LDH漏出率的抗氧化能力,(2)通过调节凋亡相关蛋白的表达的抗凋亡活性。在缺氧期间,(3)通过抑制促炎性介质发挥抗炎作用。
