Reference of 4254-15-3, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 4254-15-3, molcular formula is C3H8O2, introducing its new discovery.
Synthesis and antiretroviral evaluation of new alkoxy and aryloxy phosphate derivatives of 3′-azido-3′-deoxythymidine
A series of new ether lipid-3′-azido-3′-deoxythymidine (AZT) conjugates (11a-g) were synthesized and evaluated for anti-HIV activity. The effect of chirality on the antiviral activity was examined through the synthesis of AZT conjugates bearing alkoxypropanols in the lipid portion of the molecule (11a-d). In addition, the long alkyl chain of alkoxyethyl ether lipid-AZT analogs was replaced with aromatic groups (11e-g), and the effect of this structural modification on activity is reported. The results of the biological tests indicate that analogs with a methyl group alpha to the phosphate moiety (11c,d) exhibit a marked degree of stereoselectivity with regard to their anti-HIV activity. Also, replacement of the long alkyl chain with aromatic groups in the oxyalkyl ether phospholipid-AZT conjugates leads to substantially more potent compounds (11e-g) with an anti-HIV activity comparable to that of AZT.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 4254-15-3 is helpful to your research. Reference of 4254-15-3
