  Anti-Cancer Activity of 2,4-Disubstituted Thiophene Derivatives: Dual Inhibitors of Lipoxygenase and Cyclooxygenase

  摘要：

  合成了2,4-二取代噻吩衍生物，并针对花生四烯酸代谢中的两个重要酶系评估了其抗炎和抗癌活性。脂氧合酶和环氧合酶在慢性炎症和致癌过程中起着至关重要的作用。先前的研究表明，COX-2和5-LOX在多种癌症类型中高度激活；因此，抑制这些临床重要酶系构成了抑制肿瘤进展和转移的基本标准。在测试的衍生物中，2d和2g化合物作为脂氧合酶和环氧合酶的强效抑制剂脱颖而出。进一步对环氧合酶的强效抑制剂进行了体外细胞毒性测试，针对宫颈癌细胞（HeLa细胞）和使用EAT荷瘤小鼠的体内肿瘤模型研究，其中2-(3,4,5-三甲氧基苯基)-4-(N-甲基吲哚-3-基)噻吩（2g）表现出显著活性。此外，计算模型结果证实了活性催化配体结合口袋的存在，这从2d和2g的高原子接触能值与标准药物相比得到了证实。因此，2g可能在炎症管理和促凋亡治疗工程中得到更好的应用。

  A new regiospecific route to 2,4-disubstituted thiophenes has been developed through Simmon-Smith reaction on beta-methylthio-alpha,beta-unsaturated ketones. Extension of the reaction to beta-ethylibenzylthio-alpha,beta-unsaturated ketones also gave the corresponding 2,4-disubstituted thiophenes in a regiospecific manner. A probable mechanism involving a carbenoid methylene insertion to divalent sulfur followed by intramolecular aldol condensation has been suggested.[GRAPHICS](C) 2012 Elsevier Ltd.

  2,4-Disubstituted thiophene derivatives were synthesized and assessed for antiinflammatory and anti-cancer activities by targeting two important enzymes of the arachidonic acid metabolism. Both lipoxygenase and cyclooxygenase enzymes play vital role in chronic inflammation and carcinogenesis. Previous studies have proved that COX-2 and 5-LOX are highly activated in various types of cancers; hence inhibition of these clinically important enzymes constitutes the essential criterion for the suppression of tumor progression and metastasis. Among the tested derivatives, 2d and 2g compounds emerged as potent inhibitors of lipoxygenase and cyclooxygenase enzymes. The potent inhibitor of cyclooxygenase was further tested for in vitro cytotoxicity on cervical cancer (HeLa) cells and in vivo tumor model studies using EAT bearing mice where 2-(3,4,5- trimethoxyphenyl)-4-(N-methylindol-3-yl) thiophene (2g) showed eloquent activity. Further, in silico modeling results confirmed the active catalytic ligand binding pockets, which is evident from higher atomic contact energy values of 2d and 2g than compared to standard drug. Thus, 2g may find better application in management of inflammation and in proapoptotic therapeutic engineering.
