Synthesis of Rupestonic Acid L-Ephedrine Derivatives with Preliminary In vitro Anti-influenza Viral Activity
CONCLUSION: The rupestonic acid L-ephedrine ester (A) and rupestonic acid L-ephedrine complex (B) were synthesized and characterized using 1H NMR and 13C NMR. Moreover, their purity was determined by HPLC. Both compounds A and B exhibited more potent activities against the strains of A/PR/8/34 (H1N1) and A/FM/1/47 (H1N1) than rupestonic acid. Compound A can be regarded as a very promising lead compound for the development of anti-influenza inhibitors. Based on these results, more rupestonic acid derivatives will be designed and synthesized in the future for the development of anti-influenza inhibitors.PMID:38623973 | DOI:1...

Discovery andsynthesis of novel benzoylhydrazone neuraminidase inhibitors
Bioorg Med Chem Lett. 2024 Apr 10:129743. doi: 10.1016/j.bmcl.2024.129743. Online ahead of print.ABSTRACTNeuraminidase (NA) serves as a promising target for the exploration and development of anti-influenza drugs. In this work, lead compound 5 was discovered through pharmacophore-based virtual screening and molecular dynamics simulation, and 14 new compounds were obtained by modifying the lead compound 5 based on pharmacophore features. The biological activity test shows that 5n (IC50 = 0.13 μM) has a better inhibitory effect on wild-type NA (H5N1), while 5i (IC50 = 0.44 μM) has a prominent inhibitory effect on mutant NA...

Discovery of novel polyheterocyclic neuraminidase inhibitors with 1,3,4-oxadiazole thioetheramide as core backbone
Eur J Med Chem. 2024 Mar 12;269:116305. doi: 10.1016/j.ejmech.2024.116305. Online ahead of print.ABSTRACTInspired by our earlier findings regarding neuraminidase (NA) inhibitors interacting with 150-cavity or 430-cavity of NA, sixteen novel polyheterocyclic NA inhibitors with 1,3,4-oxadiazole thioetheramide as core backbone were designed and synthesized based on the lead compound ZINC13401480. Of the synthesized compounds, compound N5 targeting 150-cavity exerts the best inhibitory activity against the wild-type H5N1 NA, with IC50 value of 0.14 μM, which is superior to oseltamivir carboxylate (OSC) (IC50 = 0.31 μM). Comp...

Oseltamivir enhances 5-FU sensitivity in esophageal squamous carcinoma with high SPNS1
Biomed Pharmacother. 2024 Mar 8;173:116367. doi: 10.1016/j.biopha.2024.116367. Online ahead of print.ABSTRACTSphingolipid transporter 1 (SPNS1) is a significant differentially expressed gene (DEGs) in esophageal squamous cell carcinoma (ESCC). According to 3 pairs clinic cohorts, transcriptomic (155 pairs of ESCC samples and GSE53624, and proteomic data from PXD021701 including 124 ESCC samples) we found that SPNS1 was significantly higher in ESCC tissues compared to adjacent normal esophagus tissues. ESCC patients with high SPNS1 had a significantly poorer clinical prognosis than those with low SPNS1. Knockdown of SPNS1 s...
