Plinabulin(NPI-2358) Chemische Eigenschaften,Einsatz,Produktion Methoden

• Definition

  ChEBI: Plinabulin is a member of the class of 2,5-diketopiperazines that is piperazine-2,5-dione substituted by benzylidene and (5-tert-butyl-1H-imidazol-4-yl)methylidene groups at positions 3 and 6, respectively. It is a vascular disrupting agent and a microtubule destabalising agent which was in clinical trials (now discontinued) for the treatment of non-small cell lung cancer. It has a role as a microtubule-destabilising agent, an antineoplastic agent, an apoptosis inducer and an angiogenesis inhibitor. It is a member of 2,5-diketopiperazines, a member of imidazoles, a member of benzenes and an olefinic compound.

• Biologische Aktivität

  the ic50 values of npi-2358 is 9.8 ± 2.4 nmol/l, 18 ± 5 nmol/l, 13 ± 1 nmol/l, 14 ± 2 nmol/l, 18 ± 1 nmol/l and 11 nmol/l for ht-29, du 145, pc-3, mda-mb-231, ncl-h292 and jurkat cell lines, respectively[1].plinabulin (npi-2358) is a vascular disrupting agent which binds to the colchicine-binding site of tubulin. npi-2358 could destabilize tumor vascular endothelial architectural resulting in selective collapse of established tumor vasculature [1].

• in vitro

  npi-2358 exhibited anti-tumor activity against various human tumor cell lines. in proliferating human umbilical vein endothelial cells (huvecs), administration of npi-2358 at 10 nmol/l induced tubulin depolymerization within 30 min [1]. in an in-vitro model of tumor vascular collapse, npi-2358 increased huvec monolayer permeability in a dose-dependent manner. plinabulin had also shown the in-vitro cytotoxic activity with ic50 values of 11 ± 5 nmol/l and 4.3 ± 2.2 nmol/l for mes-sa and hl-60 tumor cell lines, respectively[1].

• in vivo

  in the foot implanted c3h mammary carcinomas or leg implanted kht sarcomas mice model, 7.5 mg/kg plinabulin (intraperitoneally injected) significantly reduced the transfer constant (k(trans)) and the initial area under curve (iauc) within 1 hour after injection, reaching a lowest point at 3 h, but returning to normal within 24 h. a dose-dependent decrease in iauc and k(trans) was seen at 3 h. 12.5 mg/kg and 1.5 mg/kg npi-2358 showed significant anti-tumour effects in the c3h tumours and the kht sarcoma, respectively .
