A series of 1-(1H-1,2,4-triazol-1-yl)-2-(2,4-difluorophenyl)-3-[(4-substitutedphenyl)-piperazin-1-yl]-propan-2-ols have been designed and synthesized on the basis of the structure-activity relationships and antimycotic mechanism of azole antifungal agents. Their structures were confirmed by elemental analysis, IR, MS and (1)H NMR. Results of preliminary antifungal tests against eight human pathogenic fungi (Candida albicans, Candida parapsilosis, Candida tropicalis, Cryptococcus neoformans, Aspergillus fumigatus, Trichophyton rubrum, Fonsecaea compacta, and Microsporum gypseum) in vitro showed that all title compounds exhibited activity against fungi tested to some extent. Among the compounds tested, all compounds showed higher activity against C. albicans than fluconazole in vitro. Compounds 3, 6-8, 28, 29, and 32 exhibited the same activities against C. albicans as voriconazole (with the MIC value of 0.0152microg/mL). Compounds 3, 6, and 7 showed higher activity against C. parapsilosis than all five positive controls.

Dengue is one of the most prevalent viruses transmitted by the Aedes aegypti mosquitoes. Currently, no specific medication is available to treat dengue diseases. The NS2B-NS3 protease is vital during post-translational processing, which is a key target in this study.

Borneol, a compound found in resin-rich plants, is known for its aromatic and therapeutic properties. Widely used in countries, such as China, Japan, and Southeast Asia, borneol has also demonstrated efficacy in nanodrug administration. The primary objective of this study is to understand how borneol induces oxidative stress, its impact on the attraction and repulsion of , and its acute toxicity.

Vitamin B (cobalamin, herein B) is a key cofactor for most organisms being involved in essential metabolic processes. In microbial communities, B is often scarce, largely because only few prokaryotes can synthesize B and are thus considered B-prototrophs. B-auxotrophy is mostly manifested by the absence of the B-independent methionine synthase, MetE.

Polyethers are versatile materials extensively used in advanced as well as everyday applications. The incorporation of primary amine functionality into polyethers is particularly attractive due to its well-established coupling chemistries. However, the inherent nucleophilicity of amine group poses a challenge in the anionic ring-opening polymerization (ROP) of epoxides and requires the use of robust protecting groups that can withstand the harsh conditions of ROP without triggering undesirable side reactions.

Environmental conditions significantly influence the metabolic composition and quality attributes of fruits. This study investigated the impact of altitude-associated environmental variation on flavonoid profiles and fruit quality parameters by comparing the "Red Face" strawberry variety grown in two distinct locations: high-altitude-associated environmental conditions in Zhaotong and low-altitude conditions in Dandong. Using LC-MS/MS analysis, we identified 163 bioactive flavonoids, comprising 85 flavonols, 37 flavanones, 33 flavones, and 8 flavanonols.
