To explore the more active antitumor compounds, two series of new xanthones, containing 1,4-disubstituted-1,2,3-triazole moiety were designed and synthesized. Eaton’s Reagent and “click reaction” were used in the synthesis. Most of the title compounds showed good inhibitory activity against the hepatoma carcinoma cell line (Bel-7402) and human cervical carcinoma cell line (HeLa) in vitro. Compounds 10a, 10e, 10f, 11r and 11t had potent activity with IC50 values, ranging from 2.2 ± 0.17 to 7.1 ± 0.27 μM, which was equivalent to Doxorubicin.

A series of novel azoles (a-v), which are analogues of fluconazole, have been designed and synthesized as potential antifungal agents by the click reaction. The click reaction approach toward the synthesis of novel 1,2,3-triazolyl linked triazole antifungal derivatives a-v was achieved by Cu(I)-catalyzed 1,3-dipolar cycloaddition of propargylated intermediate 5 with substituted azidomethyl benzene. In addition, the target compounds tested can increase antifungal activity.

A series of novel 1, 2, 4-triazole derivatives (9a-p) have been designed and synthesized as the potential antifungal agents. All compounds were characterized by 1H-NMR, 13C-NMR, and LCMS. Their antifungal activities against seven human pathogenic fungi were evaluated in vitro by measuring the minimal inhibitory concentrations. Most of the tested compounds were found to be more potent against Candida albicans than the control drug fluconazole.

Lactiplantibacillus plantarum (L. plantarum) ST was isolated from De’ang pickled tea in Yunnan Province, China. The genomes of strain ST were fully sequenced and analyzed using the PacBio RS II sequencing system. Our previous study has shown that L. plantarum ST is a potential probiotic strain. It had strong tolerance in the simulated artificial gastrointestinal tract, and in the antagonism tests, this strain showed strong antibacterial activity. Therefore, as a probiotic, it may be used in animal breeding. L. plantarum ST genome was composed of 1 circular chromosome and 7 plasmids. The length of the whole genome was 3320817 bp, and the annular chromosome size was 3058984 bp, guanine + cytosine (G ± C) content (%) was 44.76%, which contained 2945 protein-coding sequences (CDS). This study will contribute to a further comprehensive understanding of L. Plantarum ST at the genomic level and provide a theoretical basis for its future application in animal breeding.

A series of fluconazole analogues containing1,2,3-triazole fragment have been designed and synthesizedon the basis of the active site of the cytochrome P45014a-demethylase (CYP51). Their structures were characterizedby 1H NMR, 13C NMR and LC–MS. The MIC80values indicate that the target compounds 1a–r showedhigher activities against nearly all the fungi tested to someextent except against Aspergillus fumigatus. Compounds1c, e, f, l and p showed 128 times higher activity (with theMIC80 value of 0.0039 mg/mL) than that of fluconazoleagainst Candida albicans and also showed higher activitythan that of the other positive controls.

A novel series of fluconazole based mimicsincorporating 1,3,4-oxadiazole moiety were designed andsynthesized. All the title compounds were characterized by1H-NMR, 13C-NMR, and Q-TOF-MS. Preliminary resultsrevealed that most of analogues exhibited significant antifungalactivity against seven pathogenic fungi. Compounds9g and 9k (MIC80 B 0.125 lg/mL, respectively) werefound more potent than the positive controls itraconazoleand fluconazole as broad-spectrum antifungal agents. Theobserved docking results showed that the 1,3,4-oxadiazolemoiety enhanced the affinity binding to the cytochromeP450 14a-demethylase (CYP51).
