In vitro

Exposure of PC-3 cells to UNBS5162 (1 µM for 5 successive days) dramatically decreases the expression of the proangiogenic CXCL chemokines. UNBS5162 displays weak in vitro antiproliferative activity with IC50 values of 17.3 μM, 16 μM, 4.7 μM, 8.5 μM, 28.8 μM, 8.9 μM, 46.5 μM, 21.2 μM, 9.1 μM in PC-3, DU-145, U373-MG, Hs683, HCT-15, LoVo, MCF-7, A549 and Bx-PC-3 cells. At 10 µM UNBS5162 markedly impairs PC-3 tumor cell growth kinetics, without inducing senescence, whereas the reverse feature is observed with respect to DU-145 cells. This difference might result from their respective p53 status and/or the extent of p16 expression. At 1 µM, UNBS5162 induces no such antitumor effects. UNBS5162 at 10 µM markedly increased the levels of heterochromatin in PC-3 cells through an increase in number of histones, at least at the mRNA levels[1]. UNBS5162 has been identified to decrease levels of CXC chemokine ligand (CXCL) chemokines, including CXCL1, CXCL5 and CXCL8, in experimental prostate cancer and has a good inhibitory effect on the proliferation of tumour cells in vitro and in vivo. It inhibits cell proliferation, invasion and migration, and promote cell apoptosis, potentially through the PI3K/AKT signalling pathway in SKOV3 ovarian cancer cells[2].

In vivo

In vivo UNBS5162 after repeat administration significantly increases survival in orthotopic human prostate cancer models. In female mice for testing the pharmacokinetic profiles of UNBS5162, Systemic exposure after oral administration of 80 mg/kg is relatively low (Cmax = 510 ng/ml and AUC0-∞ = 886 ng·h/ml) reflected in an absolute bioavailability calculated to be only 3.84%. The volume of distribution (Vd) and the total clearance are estimated to be 18.9 L/kg and 3.47 L/h per kilogram, respectively. The half-life after i.v. administration of 20-mg/kg UNBS5162 is estimated to be 3.8 hours. Post-i.v. UNBS5162 plasma levels of 10 µM are only maintained for approximately 30 minutes, whereas 1-µM levels are sustained for maximally 2 hours[1].

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

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.
