The present invention provides novel alkyl phospholipid derivatives that are useful for treating various diseases including tumors and/or pathophysiological conditions in mammals, preferably humans, that are caused by microorganisms, in particular fungi, protozoa, bacteria and/or viruses. Such alkyl phospholipids can be employed as single drugs or in the course of combination therapies, in particular for the treatment of leishmaniasis, trypanosomiasis and/or malaria.

improve oralinsulin (INS) absorption due to their limited loading capacity. Therefore, an amphiphilic polyphosphazene (PEOP) containing lipid-like octadecylphosphoethanolamine (OPA) groups and amino-modified poly(ethylene glycol) at the proper ratio was designed and synthesized in this study. It was found that PEOP can self-assemble into nano-vesicles, which displayed considerable loading capability
迄今为止,由于其负载能力有限,很少有聚合物囊泡被研究来改善口服胰岛素(INS)的吸收。因此,本研究设计并合成了一种含有类脂十八烷基磷酸乙醇胺(OPA)基团和适当比例的氨基改性聚乙二醇的两亲性聚磷腈(PEOP)。研究发现,PEOP可以自组装成纳米囊泡,利用OPA和INS相互作用的协同效应以及囊泡水腔的物理封装,对INS表现出相当大的负载能力。此外,PEOP囊泡被胃肠道的肠上皮细胞摄取后,可以促进PEOP囊泡随后的淋巴转运过程中INS的吸收,从而在体内达到更好的降血糖效果。这些结果表明 PEOP 囊泡作为口服 INS 载体用于糖尿病治疗具有巨大潜力。

A composition containing an antineoplastic alkylphospholipid, and an antineoplastic antiestrogen in a lipid vesicle; more particularly, the composition is a liposome composition which comprises (i) an antineoplastic alkylphospholipid,(ii) an antineoplastic water- or lipid-soluble antiestrogen associated in liposomal form with the antineoplastic alkylphospholipid, (iii) a nonneoplastic phospholipid, and optionally one or more of (iv) a sterol, (v) a positively or negatively charged lipid, and (vi) a PEG lipid.
