Three series of thiazolylhydrazone derivatives were designed, synthesized, and evaluated for their neuraminidase (NA) inhibitory activity against influenza virus H1N1 in vitro. Compounds 1 and 2 were synthesized via the one-pot reaction and compound 3 was synthesized in two steps. Pharmacol. results showed that the majority of the target compounds 1, 2, and 3 exhibited moderate-to-good influenza NA inhibitory activity. The NA inhibitory activity of the most active compound 2g(I) (IC50 = 7.12 μg/mL) is better than that of the lead compound A. Mol. docking was performed to study the possible interactions between I and the active site of NA. On the basis of biol. results, a preliminary structure-activity relationship (SAR) was derived and discussed. Moreover, d. functional theory (DFT) calculation was also performed to explain why the thiazolylhydrazone skeleton has NA inhibitory activity, especially I with the most potent inhibitory activity. This study involved multiple reactions and reactants, such as Ethyl 4-chloro-3-oxobutanoate (cas: 638-07-3COA of Formula: C6H9ClO3).
Ethyl 4-chloro-3-oxobutanoate (cas: 638-07-3) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids. Alkyl chlorides are versatile building blocks in organic chemistry. While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available.COA of Formula: C6H9ClO3
