Discovery of Natural Product-Based Fungicides (II): Semisynthesis and Biological Activity of Sarisan Attached 3-Phenylisoxazolines as Antifungal Agents

Many phytopathogenic fungi cause severe damage to crop yields. In continuation of our research aimed at the discovery and development of natural products-based fungicides, a series of thirty-one sarisan attached 3-phenylisoxazolines were synthesized and evaluated for their antifungal activities against five phytopathogenic fungi (B. cinerea, C. lagenarium, A. solani, F. solani, and F. graminearum). Among all title sarisan derivatives, compounds IV2, IV14 and IV23 showed potent antifungal activity against some phytopathogenic fungi. In particular, compound IV2 exhibited a broad-spectrum and more potent antifungal activity against A. solani, F. solani, and F. graminearum than the commercial fungicide Hymexazol. In addition, compounds IV2, IV14 and IV23 also displayed relative low toxicity on normal NRK-52E cells. This work will give some insights into the development of sarisan derivatives as new fungicide candidates in plant protection.

Site selective synthesis and anti-inflammatory evaluation of Spiro-isoxazoline stitched adducts of arteannuin B

A library of new spiroisoxazoline analogues of arteannuin B was synthesized through 1, 3-dipolar cycloaddition in stereoselective fashion and consequently screened for anti-inflammatory activity in RAW 264.7 macrophage cells. Three potent analogues (8i, 8 m, and 8n) were found to attenuate the LPS induced release of cytokines IL-6 and TNF-α more potently than the parent molecule. Also, the inhibition of LPS induced nitric oxide production in these cells show moderate to high efficacy. None of the three potent molecules have altered the viability of RAW 264.7 cells following 48 h incubation suggesting that the inhibition of cytokines and nitric oxide production exhibited in the cells was not due to toxicity. In addition, these compounds exhibit an IC50 range of 0.17 μM-1.57 μM and 0.09 μM-0.35 μM for the inhibition of IL-6 release and nitric oxide production respectively. The results disclose potent inhibition of pro-inflammatory mediators which are encouraging and warrant further investigations to develop new therapeutic agents for inflammatory diseases.

Triazole alcohol derivative as well as preparation method and application thereof

The invention relates to a triazole alcohol derivative as well as a preparation method and application thereof. The chemical structure of the triazole alcohol derivative is shown as a formula I, R1 represents a benzene ring or a substituted benzene ring, and substituent groups of the substituted benzene ring can be located at all positions of the benzene ring, can be mono-substituted or multi-substituted, and can be selected from a) halogen which is F and Cl; b) an electron withdrawing group which is cyano or trifluoromethyl; c ) a lower alkyl of 1-4 carbon atoms or a halogen substituted loweralkyl; and d) lower alkoxy of 1-4 carbon atoms or halogen substituted lower alkoxy. The compound of the invention has strong antifungal activity, has the advantages of low toxicity, wide antibacterial spectrum and the like, and can be used for preparing antifungal drugs.

Design, synthesis, and in vitro evaluation of novel triazole analogues featuring isoxazole moieties as antifungal agents

In order to develop novel antifungal agents, based on our previous work, a series of (2R,3R)-3-((3-substitutied-isoxazol-5-yl)methoxy)-2-(2,4-difluorophenyl)-1-(1H-1,2,4-triazol-1-yl) butan-2-ol (a1-a26) were designed and synthesized. All of the compounds exhibited good in vitro antifungal activities against eight human pathogenic fungi. Among them, compound a6 showed excellent inhibitory activity against Candida albicans and Candida parasilosis with MIC80 values of 0.0313 μg/mL. In addition, compounds a6, a9, a12, a13 and a14 exhibited moderate inhibitory activities against fluconazole-resistant isolates with MIC80 values ranging from 8 μg/mL to 16 μg/mL. Furthermore, compounds a6, a12 and a23 exhibited low inhibition profiles for CYP3A4. Clear SARs were analyzed, and the molecular docking experiment was carried out to further investigate the relationship between a6 and the target enzyme CYP51.

An efficient one-pot synthesis of 3-aryl-5-methylisoxazoles from aryl aldehydes

An efficient protocol for the one-pot preparation of alkyl 3-aryl-5-methylisoxazole-4-carboxylates from aryl aldehydes is described. This method is readily amenable to the large scale preparation of isoxazoles as well as the parallel synthesis of isoxazole libraries.

Discovery and optimization of substituted piperidines as potent, selective, CNS-penetrant α4β2 nicotinic acetylcholine receptor potentiators

The discovery of a series of small molecule α4β2 nAChR potentiators is reported. The structure-activity relationship leads to potent compounds selective against nAChRs including α3β2 and α3β4 and optimized for CNS penetrance. Compounds increased currents through recombinant α4β2 nAChRs, yet did not compete for binding with the orthosteric ligand cytisine. High potency and efficacy on the rat channel combined with good PK properties will allow testing of the α4β2 potentiator mechanism in animal models of disease.
