701213-36-7 Usage
Description
BMS 626529 is an inhibitor of HIV-1 attachment. It binds to non-ligand bound HIV-1 gp120 to inhibit HIV-1 interaction with host CD4+ T cells and subsequent HIV-1 binding and cell entry. BMS 626529 reduces infectivity of laboratory strains and clinical isolates of HIV-1 (EC50s = 0.4-2,000 and 25-2,000 nM, respectively) with cytotoxic concentration (CC50) values greater than 100 μM in a panel of mammalian cell lines.
Uses
Temsavir is a Fostemsavir (CAS# 864953-29-7) intermediate and an antiviral agent. It is an HIV-1 attachment inhibitor.
in vitro
the activity of bms-626529 is virus dependent, due to heterogeneity within gp120. bms-626529 had half-maximal effective concentration values of6 log10, with half-maximal effective concentration values in the low pm range against the most susceptible viruses. measurement of the binding affinity of bms-626529 for purified gp120 suggests that a contributory factor to its inhibitory potency may be a relatively long dissociative half-life [1].

Check Digit Verification of cas no
The CAS Registry Mumber 701213-36-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,0,1,2,1 and 3 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 701213-36:
(8*7)+(7*0)+(6*1)+(5*2)+(4*1)+(3*3)+(2*3)+(1*6)=97
97 % 10 = 7
So 701213-36-7 is a valid CAS Registry Number.

The development of two enabling routes that led to the production of >1000 kg of BMS-663068 (3) is described. The route identified for the initial 100 kg delivery to support development activities and initial clinical trials involved the conversion of 2-amino-4-picoline to the parent active pharmaceutical ingredient (API), followed by pro-drug installation and deprotection. To eliminate the problematic isolation of the parent API and synthesis of di-t-butyl(chloromethyl)phosphate, a second-generation pro-drug installation route was developed which involved the conversion of a late-stage common intermediate to an N(1)-thioether derivative followed by chloromethylation, displacement with di-t-butylpotassium phosphate, and deprotection. This second strategy resulted in the multikilogram scale preparation of the API in 14 linear steps and ～7% overall yield.
