Tumor growth is usually associated with persistent pain, especially during mid and terminal stages of cancer development. Nonetheless, a medicinal compound that possesses both anticancer and analgesic properties has not been identified. The 2-alkylthio-benzofuro[3,2-d]pyrimidin-4(3H)-ones (Code 5a–d) and 1-aryl-2-alkylthio-benzofuro[3,2-d]-1,2,4-triazolo[1,5-a]pyrimidin-5(1H)-ones (Code 10a–g) were synthesized by using the bioisostere concept, which were obtained via the aza-Wittig reaction of functionalized iminophosphoranes reacted with carbon disulfide and further reaction of the product with alkyl halides or halogenated aliphatic esters. The analgesic properties of 5a–d and 10a–g were studied using rat chronic constriction injury model and the antitumor properties of these chemicals were assessed using MTS cell proliferation assay. Results showed that 5a–d and 10a–g were found to attenuate thermal and mechanical allodynia induced by neuropathy and inhibited the proliferation of three human cancer cell lines (A459, HepG2, and HeLa). Among these compounds, 10g showed highly positive effects in both assessments, and would be selected for future work.
肿瘤生长通常伴随着持续性疼痛,尤其是在癌症发展的中晚期阶段。然而,至今尚未发现一种兼具抗癌和镇痛特性的药物化合物。通过生物等排体概念合成了2-烷硫基苯并呋喃[3,2-d]嘧啶-4(3H)-酮(代码5a–d)和1-芳基-2-烷硫基苯并呋喃[3,2-d]-1,2,4-三唑并[1,5-a]嘧啶-5(1H)-酮(代码10a–g),这些化合物是通过功能化亚胺膦与二硫化碳进行aza-Wittig反应,再与烷基卤化物或卤代脂肪酯进一步反应获得。利用大鼠慢性束缚损伤模型研究了5a–d和10a–g的镇痛特性,并使用MTS细胞增殖实验评估了这些化学物质的抗肿瘤特性。结果显示,5a–d和10a–g能减轻神经病变引起的热痛和机械痛觉过敏,并抑制三种人类癌细胞系(A459、HepG2和HeLa)的增殖。在这些化合物中,10g在两项评估中表现出了非常积极的效果,将被选中进行后续研究。
