Kinesin spindle protein (KSP) is one member of the mitotic kinesins involved in the early stages of mitosis responsible for centrosome separation. As the R form of ARRY-520, ARRY-520 R enantiomer is a synthetic, small molecule KSP inhibitor.
In vitro: ARRY-520 had low nanomolar antiproliferative activity in various tumor cell lines and exhibited activity in multidrug-resistant cell lines. EC50s of ARRY-520 for proliferation inhibition in HCT-15, NCI/ADR-RES and K562/ADR cells was 3.7, 14 and 4.2 nM, respectively, while paclitaxel EC50s in these cell lines was 35, 565 and 372 nM. Moreover, K562/ADR was found to be 118-fold resistant to paclitaxel when compared to the parent K562 line, but only 3.5-fold resistant to that of ARRY-520 [1].
In vivo: ARRY-520 was found to be active in UISO-BCA-1 xenografts, which were completely resistant to paclitaxel. The antitumor efficacy of ARRY-520 was also found to be superior to paclitaxel in mice bearing HT-29, HCT-116, MDA-MB-231 and A2780 xenografts. ARRY-520 was superior to docetaxel in the androgen receptor-negative prostate cancer PC-3 xenograft model, and was also superior to docetaxel in the DU145 prostate xenograft model [1].
Clinical trial: A phase I trial was conducted to establish the safety and the maximum tolerated dose (MTD) of ARRY-520. The MTD was 4.5 mg/m2 total dose per cycle for both dose schedules. Dose-limiting toxicities included exfoliative rash, hand-foot-syndrome, mucositis, and hyperbilirubinemia. Grades 3 or 4 reversible drug-related myelosuppression were observed in 33 of 36 patients [2].

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.
Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.
Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
