The invention provides novel compositions—lipopeptides and analogs, including somocystinamide A, and somocystinamide A variants and analogs, and pharmaceutical compositions, liposomes and nanoparticles comprising them, and methods of making and using them. In one embodiment, these lipopeptides and analogs are used to induce apoptosis in a cell, which can be a normal cell, a dysfunctional cell and/or a cancer (tumor) cell. In alternative embodiments, the compositions of the invention, including the lipopeptides and analogs of the invention, and the pharmaceutical compositions comprising them, are used to treat or ameliorate (including slowing the progression of) normal, dysfunctional (e.g., abnormally proliferating) and/or tumor associated blood vessels, including endothelial and/or capillary cell growth; including neovasculature related to (within, providing a blood supply to) a tumor.
本发明提供了新型组合物——脂肽和类似物,包括somocystinamide A和somocystinamide A的变体和类似物,以及包含它们的药物组合物、脂质体和纳米粒子,以及制备和使用它们的方法。在一种实施例中,这些脂肽和类似物被用来诱导细胞凋亡,这可以是正常细胞、功能失调的细胞和/或癌细胞。在另一种实施例中,本发明的组合物,包括本发明的脂肽和类似物以及包含它们的药物组合物,被用于治疗或改善(包括减缓进展)正常、功能失调(例如异常增殖)和/或与肿瘤相关的血管,包括内皮和/或毛细血管细胞生长;包括与肿瘤相关的新生血管(在肿瘤内部提供血液供应)。
