TPI 287 is a synthetic, third generation taxane with potential antineoplastic activity. TPI 287 binds to tubulin and stabilizes microtubules, resulting in inhibition of microtubule assembly disassembly dynamics, cell cycle arrest at the G2 M phase, and apoptosis.
PPI-2458 is a synthetic derivative of fumagillin with antineoplastic and cytotoxic properties. PPI-2458 irreversibly inhibits the enzyme methionine aminopeptidase type 2 (MetAP2), thereby preventing abnormal cell growth and angiogenesis. PPI-2458 is reported to have a better toxicity profile compared to other agents of its class.
3-epi-25-hydroxy Vitamin D3is the C-3 epimer of 25-hydroxy vitamin D3.1Dietary administration of 3-epi-25-hydroxy vitamin D3(0.5 and 1 IU g) decreases levels of serum parathyroid hormone (PTH) in male, but not female, weanling rats. 1.Djekic-Ivankovic, M., Lavery, P., Agellon, S., et al.The C-3α epimer of 25-hydroxycholecalciferol from endogenous and exogenous sources supports normal growth and bone mineral density in weanling ratsJ.
