Summary: Nematode chitinases play a critical role in the nematode life cycle, and CeCht1 is a potential target for developing novel nematicides. Lunidonine, a natural quinoline alkaloid, was found to inhibit CeCht1 activity, and a series of benzo[d][1,3]dioxole-5-carboxylate derivatives were designed and synthesized based on its predicted binding mode. Compound a12 showed strong interaction with CeCht1 and exhibited excellent in vitro nematicidal activity, making it a promising candidate for a novel chemical nematicide targeting CeCht1.

Summary: Invasive fungal infections are a serious global infectious disease. Due to the development of antifungal drug resistance, the limited efficacy of existing drugs has led to high mortality in patients. Targeting the essential eukaryotic chaperone Hsp90 as a new strategy to mitigate resistance and counter the threat of drug-resistant fungi has shown potential. Specifically, a series of 4,5-diarylisoxazole analogues have been designed and synthesized as fungal Hsp90 inhibitors, which demonstrated strong synergistic effects with fluconazole both in vitro and in vivo. Compound A17, in particular, showed the ability to avoid potential mammalian toxicity based on key differences between humans and fungi. These findings support the feasibility of targeting fungal Hsp90 as a promising antifungal strategy and further development of compound A17 as a valuable research probe for investigating fungal Hsp90.

Summary: Despite the availability of vaccines, monoclonal antibodies, and restrictions, there is a strong demand for new antiviral drugs that are both effective and safe against COVID-19. This study describes the design, synthesis, and biological activity of peptidomimetic covalent reversible inhibitors targeting the viral 3-chymotrypsin-like protease (3CLpro) which is essential for viral replication. These inhibitors showed potent activity against multiple coronaviruses, including SARS-CoV-2, MERS-CoV, and HCoV 229. The results suggest that these inhibitors have the potential to be developed as broad-spectrum antiviral drugs against future coronavirus pandemics.

Summary: This study aimed to design new polysubstituted pyrrole derivatives as selective acetylcholinesterase inhibitors for Alzheimer's disease treatment. A diverse range of polysubstituted pyrroles was synthesized through a sequential domino strategy, and compound 4ad showed the highest potency and selectivity against acetylcholinesterase. The compound inhibited acetylcholinesterase in an uncompetitive mode, and molecular modeling revealed its proper fit and stabilization in the enzyme's active site.

Summary: This study presents an in silico strategy for the synthesis of chiral N- and O-heterocycles using a modified limonene epoxide hydrolase as a catalyst. By reshaping the active site, the reprogrammed enzyme enables the catalysis of Baldwin-type cyclizations, leading to high conversion rates and enantiomeric ratios.

Summary: ProTide and cyclic phosphate ester are two successful prodrug technologies to enhance the efficacy of nucleoside drugs. In this study, we designed novel ProTide and cyclic phosphate ester prodrugs of gemcitabine. The cyclic phosphate ester derivative 18c showed significantly higher anti-proliferative activity compared to the positive control, with potent cytotoxicity and prolonged anti-tumor activity. Moreover, we separated and characterized the two P chiral diastereomers of gemcitabine cyclic phosphate ester prodrugs for the first time, highlighting their similar potency and metabolic profile. Compound 18c exhibited promising in vivo anti-tumor activity in prostate and pancreatic cancer models.

Summary: This study found that ex-oTau affects the uptake of extracellular glutamate by astrocytes, leading to dysregulated glutamate signaling and impaired Na+-dependent transport. This is caused by reduced expression and altered function of glutamate-transporter-1 and mislocalization of NKA1A1 and NKA1A2.
