The natural product salicylihalamide is a potent inhibitor of the Vacuolar ATPase (V-ATPase), a potential target for antitumor chemotherapy. We generated salicylihalamide-resistant tumor cell lines typified by an overexpansion of lysosomal organelles. We also found that many tumor cell lines upregulate tissue-specific plasmalemmal V-ATPases, and hypothesize that tumors that derive their energy from
天然产物水杨酰胺是液泡 ATP 酶 (V-ATPase) 的有效抑制剂,是抗肿瘤化疗的潜在靶点。我们产生了以溶酶体细胞器过度扩张为代表的抗水杨酰胺的肿瘤细胞系。我们还发现许多肿瘤细胞系上调组织特异性质膜 V-ATP 酶,并假设从糖酵解中获得能量的肿瘤依赖于这些亚型来维持中性细胞质 pH。为了进一步验证 V-ATPase 抑制剂作为癌症化疗先导物的潜力,我们开发了有效的水杨酰卤酰胺类似物 saliphenylhalamide 的多克合成。
