Sample solution is provided at 25 µL, 10mM.
GSK3494245 (DDD01305143) is a potent, orally active, and selective inhibitor of the chymotrypsin-like activity of the parasite proteasome binding in a site sandwiched between the β4 and β5 subunits (IC50=0.16 μM for WT L. donovani proteasomes). GSK3494245 moderately inhibits chymotrypsin-like activity of human proteasome (IC50: purified 26S=13 µM; enriched THP-1 extracts IC50=40µM). GSK3494245 exhibits attractive biological and biosafety properties[1][2].
GSK3494245 shows EC50 value of 5.7 μM in L. donovani intramacrophage assay, where the amastigotes are cultured in differentiated THP-1 cells. GSK3494245 demonstrates good selectivity over mammalian cell growth inhibition (THP-1 cells; EC50 > 50 μM)[1].GSK3494245 (DDD01305143) shows pEC50s of 6.5 and 5.8 against axenic amastigote and ld InMac, respectively. Ld InMac is the intramacrophage assay carried out in THP-1 cells with L. donovani amastigote[2].
GSK3494245 (25 mg/kg; orally twice a day for 10 consecutive days) elicits a >95% reduction of parasite load in Infected mice (L. donovani, LV9)[1].

DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL,
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL saline,混匀澄清。
1. 首先保证母液是澄清的;
2.
一定要按照顺序依次将溶剂加入,进行下一步操作之前必须保证上一步操作得到的是澄清的溶液,可采用涡旋、超声或水浴加热等物理方法助溶。
