The multicomponent reaction of aldehydes, benzoylisothiocyanate and alkyl bromides in the presence of ammonium acetate, sodium cyanide and a catalytic amount of KF/Clinoptilolite nanoparticles (KF/CP NPs) in the water at 100°C was investigated. In these reactions, thiazole I [R= H, Me, i-Pr; R¹ = ethoxycarbonyl, 4-methoxyphenyl, 4-bromophenyl] were produced in good to excellent yields and short time. Also, the antioxidant activity was studied for some newly synthesized compounds using the DPPH radical trapping and reducing of ferric ion experiments and compared the results with synthetic antioxidants (TBHQ and BHT). As a result, the compounds I [R= i-Pr; R¹ = ethoxycarbonyl] showed excellent DPPH radical trapping and reducing the strength of ferric ion. These compounds I [R= H, Me, i-Pr; R¹ = ethoxycarbonyl, 4-methoxyphenyl, 4-bromophenyl] have biol. potential because of the thiazole core.

Han, Guiyan;Liu, Na;Li, Chenglan;Tu, Jie;Li, Zhuang;Sheng, Chunquan research published ã€?Discovery of Novel Fungal Lanosterol 14α-Demethylase (CYP51)/Histone Deacetylase Dual Inhibitors to Treat Azole-Resistant Candidiasisã€? the research content is summarized as follows. Invasive fungal infections (particularly candidiasis) are emerging as severe infectious diseases worldwide. Because of serious antifungal drug resistance, therapeutic efficacy of the current treatment for candidiasis is limited and associated with high mortality. However, it is highly challenging to develop novel strategies and effective therapeutic agents to combat drug resistance. Herein, the first generation of lanosterol 14α-demethylase (CYP51)-histone deacetylase (HDAC) dual inhibitors was designed, which exhibited potent antifungal activity against azole-resistant clin. isolates. In particular, compounds 12h(II) and 15j(I) were highly active both in vitro and in vivo to treat azole-resistant candidiasis. Antifungal mechanism studies revealed that they acted by blocking ergosterol biosynthesis and HDAC catalytic activity in fungus, suppressing the function of efflux pump, yeast-to-hypha morphol. transition, and biofilm formation. Therefore, CYP51-HDAC dual inhibitors represent a promising strategy to develop novel antifungal agents against azole-resistant candidiasis.

The authors prepared four structurally modified bis-tert-alc. functionalized crown ether-strapped calix[4]arene promoters, i.e., bis-tert-alc. functionalized crown-5-calix[4]arene (BA5C), bis-tert-alc. functionalized crown-7-calix[4]arene (BA7C), bis-1,1-dimethylbutanol functionalized crown 6-calix[4]arene (B3A6C), and bis-1,1-dimethylhexanol functionalized crown 6-calix[4]arene (B5AC6C). Nucleophilic fluorinations were conducted using alkali metal fluorides to study phase-transfer catalytic activities with respect to the sizes of crown ether-strapped calix[4]arene (CEC) subunits and lengths of alkyl chain spacers between tert-alc. and CEC subunits. The reactivity of potassium fluoride was significantly enhanced by BA5C promoter because its crown-5-calix[4]arene subunit had cavity size appropriate for K⁺ capture. In contrast, BA7C did not efficiently enhance cesium fluoride S_N2 fluorination because its crown-7-calix[4]arene cavity was too large to capture Cs⁺. The alkyl spacer of bis-tert-alc. functionalized CEC provided sufficient distance between F^– and Cs⁺. In particular, the three-component alkyl carbon chain of B3A6C was optimal in terms of increasing CsF reactivity. Systematic quantum chem. anal. predicted that fluorination reactions facilitated by bis-tert-alc.-substituted crown-6-calix[4]arene (BACCA) and B3A6C might proceed via separated ion-pair type pre-reaction complexes, which suggested that these two promotors act as Lewis bases that essentially sep. CsF ion-pairs. The lower (by 0.4 kcal/mol) Gibbs free energy of activation for the reaction promoted by B3A6C than that facilitated by BACCA concurred with the exptl. observed slightly greater efficiency of B3A6C than BACCA.

Construction of an activatable photosensitizer and integration into an adaptive nanozyme during phototherapy without producing off-target toxicity remains a challenge. Herein, we have fabricated a prodrug-like supramol. nanozyme based on a metallic-curcumin and cyanine co-assembly. The albumin-mediated phenol AOH group transformation of nanozyme changes its adjustable oxygen stress from neg. superoxide dismutase-like activity of ROS-scavenging to pos. photo oxidase activity with an ROS-amplifying capacity. It further increases the depth penetration of a nanozyme in a tumor spheroid, selectively targeting tumorous phototherapy. It also triggers a signal in targeted tumor cells and helps increase cancer cell ablation. This work suggests new options for development of activatable supramol. nanozymes and provides a synergetic prodrug-like nanozyme strategy for early diagnosis and preclin. phototherapeutics.

The compound is characterized by spectrometric, spectroscopic and single crystal (SC-XRD) techniques. Non-covalent interactions that are responsible for crystal packing are explored by Hirshfeld surface anal. All theor. calculations were performed by DFT quantum chem. methods using 6-311G(d,p) and cc-pVTZ basis sets and compared. Theor. harmonic frequencies of Et 2-[2-(2-nitrobenzylidene)hydrazinyl]thiazole-4-carboxylate were optimized.
