틸로포린

개요Tylophorine is an alkaloid first isolated in 1935 from plants of the genus Tylophora. Studies have demonstrated that this class of alkaloids, characterized by a phenanthroindolizidine skeleton, exhibits potent antitumor, anti-inflammatory, and antiviral activities. A representative tylophorine analogue, DCB-3503 (NSC-716802, 1), displayed an average GI₅₀ value of approximately 10⁻⁸ M against 59 human tumor cell lines in the National Cancer Institute (NCI) anticancer drug screening panel and also inhibited the proliferation of multidrug-resistant tumor cells. Tylocrebrine, another representative member of this class, advanced to Phase I clinical trials as a potential antitumor agent but was subsequently withdrawn because of severe neurotoxicity. Although extensive studies have investigated the antitumor mechanisms of tylophorine alkaloids, their direct molecular targets remain unclear.[1]
