Lenalidomide As a means of enhancing the immunomodulatory effects and Bicalutamide beating the nonhematological adverse events of thalidomide, analogs including lenalidomide have now been produced. Like thalidomide, lenalidomide exerts pleiotropic effects, including immunomodulatory, anti-angiogenic, and anti-neoplastic activities. In pre-clinical studies, more potent anti MM activity have been demonstrated by lenalidomide than its parent compound and its toxicity profile is more favorable. After comprehensive phase I and phase II trials in advanced level MM, followed by two pivotal phase III trials, lenalidomide was authorized by the US FDA and by the European Medicines Agency in June 200770 for use in conjunction with dexamethasone in the treatment of MM in patients who've received one or more prior therapy. Mechanism of action in MM The molecular mechanisms related to infection Cholangiocarcinoma progression in MM are influenced by the interaction between the bone marrow microenvironment and MM cells. Fleetingly, the adhesion of MM cells to bone marrow stromal cells triggers the release of cytokines that mediate independent pathways of MM cell growth and success, including antiapoptosis, proliferation, cell cycle progression, and migration. Stromal cell derived IL 6, tumor necrosis factor alpha and vascular endothelial growth factor, for instance, take part in the activation of many MM cell signaling pathways, including phosphatidylinositol 3 kinase /Akt, Janus kinase /signal transducer and activator of transcription 3, Raf/Mek/ mitogen activated protein kinase, and NF T, as well as their downstream targets. Lenalidomide continues to be demonstrated to influence most of the interactions central to myeloma pifithrin- development by both direct and indirect systems. The immediate effects of lenalidomide include induction of apoptosis or cell cycle arrest of indirect effects and the tumor cell involving change of the tumor microenvironment and augmentation of the innate and acquired immune responses. Combined, these effects end in effective cyst cell reduction and reduction. This duality of action might be crucial in the treatment of MM. The development of lenalidomide as an anticancer agent followed the success of thalidomide, a potent inhibitor of T cell costimulatory activity and TNF with antiangiogenesis activity. Compared with its parent compound, lenalidomide is just a stronger inhibitor of TNFsecretion by activated monocytes. In addition to TNF, lenalidomide also inhibits transforming growth factor beta and the pro-inflammatory cytokines, IL 1, IL 6, and IL 12, while release of the anti-inflammatory cytokine IL 10 seems to be improved by lenalidomide.
