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.

Ces composés comprennent une fraction bio-active qui contient une substance thérapeutiquement active et qui est liée par une fraction de liaison à au moins un substituant hydrocarboné choisi de sorte que le composé soit suffisamment non-polaire pour conférer audit composé une capacité de liaison avec des lipides. Les composés découlant de cette invention sont ansi utiles pour apporter des agents thérapeutiques en des sites spécifiques et les y maintenir. On décrit des procédés concernant l'utilisation de différents composés de l'invention dans le traitement de maladies ou autres états pathologiques, par exemple: 1) la resténose consécutive à une angioplastie, 2) l'arthrite rhumatoïde; 3) la prolifération de cellules tumorales, surtout de cellules du cancer des ovaires; et 4) le psoriasis.
