Compounds are provided having the capability of binding therapeutically active substances to lipid containing bio-compatible particles, such as cells or viruses. These compounds include a bio-affecting moiety, comprising a therapeutically active substance, which is linked via a linking moiety to at least one hydrocarbon substituent selected so that the compounds is sufficiently non-polar to impart lipid binding capability to the compound. Thus, compounds of the invention are useful for site-selective delivery of therapeutic agents, and retention thereof at the selected site. Methods are provided for using various compounds of the invention in treatment of diseases or other pathological conditions. For example, methods are provided for treatment of: (1) post-angioplasty restenosis; (2) rheumatoid arthritis; (3) tumor cell proliferation, particularly tumor cells associated with ovarian cancer; and (4) psoriasis.
提供了一种化合物,具有将治疗活性物质结合到含脂质的
生物相容颗粒(如细胞或病毒)的能力。这些化合物包括一个
生物影响基团,包括一个治疗活性物质,该物质通过一个连接基团连接到至少一个碳氢化合物取代基,所选的取代基足够非极性,以赋予该化合物脂质结合能力。因此,本发明的化合物对于治疗剂的位点选择性传递以及在所选位点的保留是有用的。提供了使用本发明的各种化合物治疗疾病或其他病理状况的方法。例如,提供了用于治疗以下情况的方法:(1)血管成形术后再狭窄;(2)类风湿性关节炎;(3)肿瘤细胞增殖,特别是与卵巢癌相关的肿瘤细胞;以及(4)牛皮癣。
