描述 | The mammalian target of rapamycin (mTOR/FRAP1) is a serine/threonine protein kinase, which belongs to a family of phosphoinositide 3-kinase-related kinases (PIKK). mTOR is the catalytic subunit of two signaling complexes called mTORC1 and mTORC2, which play a critical role in regulation of cell metabolism, proliferation, survival and migration. CZ415 is a potent and highly selective ATP-competitive mTOR inhibitor with Kdapp value of 6.9 nM, and shows efficacy in a semi-therapeutic collagen induced arthritis (CIA) mouse model[3]. CZ514 (1-1000 nM) dose-dependently inhibited human papillary thyroid carcinoma cell line TPC-1 cell growth, induced cleavage of both caspase-3 and caspase-9 and disrupted cycle progression. Consistently, oral administration of CZ415 (20 mg/kg body weight, daily for 24 days) significantly reduced TPC-1 xenograft tumor volume in mice more than 60%[4]. CZ415 dose-dependently inhibited HepG2 cell survival with IC50 of 233.75 ±22.54 nM. HepG2 tumor growth in SCID mice was decreased to 13.93 ± 3.72 mm3 after oral administration of CZ415 (10 mg/kg body weight, daily), compared with 43.52 ± 4.5 mm3 in vehicle control mice[5]. It was also found that CZ415 (from 1 to 300 nM) dose-dependently inhibited head and neck squamous cell carcinoma cell line SCC-9 survival[6]. | ||
