Description of ARQ 621

ARQ 621 is a novel, allosteric,potent and selective inhibitor of Eg5. Eg5 is a member of the mitotickinesin superfamily which plays a key role in mitosis. Eg5 is essential for the dynamic organization of the mitotic spindle. Over-expression of Eg5 leads to genomic instability and tumor formation [1].

In vitro: In human liver microsomes, t1/2 of ARQ 621 was 53 min. The t1/2value of ARQ 621 in male and female mouse, rat, dog and monkey liver microsomes was 43, 53, 56, 53, 47, 44, 36, and 32 minutes, respectively [1]. IC50value of ARQ 621 for CYP 1A2, 2C9, 2D6, 3A4, 2C19, and 2C8 was>20, >20, >20, 4.1, 4.0, and 15 µM, respectively. ARQ 621 showed anti-tumor activity with potencies in the low nanomolar range across a range of human solid and hematological malignanciescancer cell types such as colon, NSCLC, gastric, and hematologic cancer cell lines [1].

In vivo: Oral administration of ARQ 621 showed that the bioavailability of ARQ 621 was approximately 9% [1].

Clinical trial: ARQ 621 was currently being tested in a Phase I clinical trial in cancer patients. ARQ 621 (10 mg/m2/week) was administered weekly intravenously over 1-2 hours. Adverse events emerged in 95.9% patients. The main drug-related side-effects were fatigue, acute intravascular hemolysis, and abdominal pain. ARQ 621 appeared to be well tolerated at the weekly dose of 280mg/m2[2,3].

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 saline, 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.
