102042-09-1 Usage
Uses
Different sources of media describe the Uses of 102042-09-1 differently. You can refer to the following data:
1. 21-Hydroxyoligomycin A is a rare member of the oligomycin class isolated as a co-metabolite of nemadectin, hence its original naming as nemadectin omega. Only limited literature references to this metabolite are available. However, in-house testing suggests that 21-hydroxyoligomycin has a more selective action against mammalian tumour cell lines than oligomycin A, exhibiting only weak antifungal and nematocidal activity.
2. 21-Hydroxyoligomycin A is an oligomycin antibiotic coisolated with nemadectins.
Biological Activity
21-hydroxy oligomycin a is an antibiotic which was first isolated from s. cyaneogriseus ssp.noncyanogenus [1]. 21-hydroxy oligomycin a functions as μm inhibitor of the multidrug efflux pump p-gp, and low nm inhibitors of k-ras pm localization [1].cancer cell viability screening confirmed that 21-hydroxy oligomycin a was cytotoxic to human colorectal carcinoma cells (ic50 > 3 μm), and was inhibitor of the abc transporter efflux pump p-glyco-protein (p-gp). significantly, 21-hydroxy oligomycin a was exceptionally potent inhibitor of k-ras pm localisation with emax of 0.67–0.75 and an ic50 of 1.5–14 nm [1]. 21-hydroxy oligomycin a was inhibitor of k-ras pm localisation in mdck cell with an ic50 of 4.82 ± 0.70 nm. 21-hydroxy oligomycin a was moderately cytotoxic towards both sw620 and sw620 ad300 cells with the ic50 of 14.4 ± 0.6 and 11.8 ± 3.1 μm, respectively. in the flow cytometry assay, 21-hydroxy oligomycin a (20 μm) increased intracellular calcein fluorescence significantly when compared with the negative control [1].

Check Digit Verification of cas no
The CAS Registry Mumber 102042-09-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,0,4 and 2 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 102042-09:
(8*1)+(7*0)+(6*2)+(5*0)+(4*4)+(3*2)+(2*0)+(1*9)=51
51 % 10 = 1
So 102042-09-1 is a valid CAS Registry Number.
