| Plinabulin(NPI-2358) Usage And Synthesis |
| Biological Activity | 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 . | | references | nicholson b1, lloyd gk, miller br, palladino ma, kiso y, hayashi y, neuteboom st. npi-2358 is a tubulin-depolymerizing agent: in-vitro evidence for activity as a tumor vascular-disrupting agent.anticancer drugs. 2006 jan; 17(1):25-31.bertelsen l b, shen y y, nielsen t, et al. vascular effects of plinabulin (npi-2358) and the influence on tumour response when given alone or combined with radiation[j]. international journal of radiation biology, 2011, 87(11): 1126-1134.millward m, mainwaring p, mita a, et al. phase 1 study of the novel vascular disrupting agent plinabulin (npi-2358) and docetaxel[j]. investigational new drugs, 2012, 30(3): 1065-1073. |
