Synthesis and pharmacodynamic evaluation of Dihydropteridone derivatives against PDCoV in vivo and in vitro
In this study, we have designed and synthesized a series of unreported Dihydropteridone derivatives. All of these compounds were evaluated for the against PDCoV in vivo and in vitro for the first time. In this study, antiviral activity (17.34 ± 7.20 μM) and low cytotoxicity (>800 μM) was found in compound W8. Compound W8 exerts antiviral effect on PDCoV by inhibiting cell apoptosis and inflammatory factors caused by virus infection in vitro. In addition, lung and small intestinal lesions caused by PDCoV infection in mice could be significantly reduced by compound W8. These findings highlight the potential of compound...

Induction of breast cancer cell apoptosis by novel thiouracil-fused heterocyclic compounds through boosting of Bax/Bcl-2 ratio and DFT study
Bioorg Chem. 2024 Mar 26;146:107292. doi: 10.1016/j.bioorg.2024.107292. Online ahead of print.ABSTRACTBreast cancer is a common public health disease causing mortality worldwide. Thus, providing novel chemotherapies that tackle breast cancer is of great interest. In this investigation, novel pyrido[2,3-d]pyrimidine derivatives 3,4,(6a-c),(8a,b),9-20 were synthesized and characterized using a variety of spectrum analyses. The geometric and thermal parameters of the novel thiouracil derivatives 3,4,6a,(8a,b),11,12,17,18, 19 were measured using density functional theory (DFT) via DFT/B3LYP/6-31 + G(d,p) basis set.

Bioorg Chem. 2024 Mar 25;146:107311. doi: 10.1016/j.bioorg.2024.107311. Online ahead of print.ABSTRACTIn the course of our investigations of antifungal natural products, the structure-activity relationship and antifungal activities of oleanolic acid-type saponins (1-28) from Pulsatilla chinensis against human and plant pathogenic fungi were elucidated. The analysis of structure-activity relationship of oleanolic acid-type saponins showed that the free carboxyl at C-28 was essential for their antifungal activities; the free hydroxyl group at the C-23 site of oleanolic acid-type saponins played a crucial role in their antifu...

Design, synthesis and biological evaluation of new 2,6-difluorinated phenyl 4-(2-oxoimidazolidin-1-yl)benzenesulfonates as new antimicrotubule agents
In this study, we evaluated the effect of the difluorination of the aromatic ring bearing the imidazolidin-2-one moiety (ring A) at positions 3, 5 and 2, 6 on their antiproliferative activity on four cancer cell lines, their ability to disrupt the microtubules and their toxicity toward chick embryos. We thus synthesized, characterized and biologically evaluated 24 new difluorinated PIB-SO derivatives designated as phenyl 3,5-difluoro-4-(2-oxoimidazolidin-1-yl)benzenesulfonates (3,5-PFB-SOs, 4-15) and phenyl 2,6-difluoro-4-(2-oxoimidazolidin-1-yl)benzenesulfonates (2,6-PFB-SOs, 16-27).

Synthesis of narrow-spectrum anti-mycobacterial molecules without effect on the diversity of gut microbiota in mice based on the structure of rifampicin
Bioorg Chem. 2024 Mar 13;146:107282. doi: 10.1016/j.bioorg.2024.107282. Online ahead of print.ABSTRACTRifampicin (RIF) is a broad-spectrum antimicrobial agent that is also a first-line drug for treating tuberculosis (TB). Based on the naphthyl ring structure of RIF this study synthesized 16 narrow-spectrum antimicrobial molecules that were specifically anti-Mycobacterium tuberculosis (Mtb). The most potent candidate was 2-((6-hydroxynaphthalen-2-yl) methylene) hydrazine-1-carbothioamide (compound 3c) with minimum inhibitory concentration (MIC) of 1 μg/mL against Mtb. Synergistic anti-Mtb test indicated that none of the co...
