Ralstonia solanacearum, the causal agent of bacterial wilt, can naturally infect a wide range of host plants. The type III secretion system (T3SS) is a major virulence determinant in this bacterium. Studies have shown that plant-derived compounds are able to inhibit or induce the T3SS in some plant pathogenic bacteria, though no specific T3SS inhibitor or inducer has yet been identified in R. solanacearum. In this study, a total of 50 different compounds were screened and almost half of them (22 of 50) significantly inhibited or induced the T3SS expression of R. solanacearum. Based on the strong induction activity on T3SS, the T3SS inducer oleanolic acid (OA) was chosen for further study. We found that OA induced the expression of T3SS through the HrpG-HrpB pathway. Some type III effector genes were induced in T3SS inducing medium supplemented with OA. In addition, OA targeted only the T3SS and did not affect other virulence determinants. Finally, we observed that induction of T3SS by OA accelerated disease progress on tobacco. Overall our results suggest that plant-derived compounds are an abundant source of R. solanacearum T3SS regulators, which could prove useful as tools to interrogate the regulation of this key virulence pathway.

Isoxazole is an azole with an oxygen atom next to the nitrogen. Isoxazole rings are found in some natural products, such as ibotenic acid and also found in a number of drugs, including COX-2 inhibitor valdecoxib. Furoxan, a nitric oxide donor is containing isoxazolyl group and found in many beta-lactamase resistant antibiotics, such as cloxacillin, dicloxacillin and flucloxacillin. The synthetic androgenic steroid danazol also has an isoxazole ring. The substituted isoxazoles are well developed in literature to possess significant biological activities. The disubstituted and trisubstituted isoxazoles have been reported to exhibit broad range of biological activities such as antimicrobial activity, analgesic activity, anti-inflammatory activity, antioxidant activity, anticancer activity, CNS (central nervous system) activity, antitubercular activity and miscellaneous activities like GABA (gamma-amino butyric acid) agonistic activity, inhibitory activity, antihypertensive activity, and glutamate transporter activity. The present review summarizes up to date information of various biological activities of isoxazole analogs.

The appropriate choice of redox mediator can avoid electrode passivation and overpotential, which strongly inhibit the efficient activation of substrates in electrolysis. In a patent, 2682-49-7, name is Thiazolidin-2-one, introducing its new discovery. name: Thiazolidin-2-one

Background: Thienopyrimidine, triazole and thiazolidinone derivatives have recently gained attention due to their effective pharmacological activities. They show antioxidant, antitumor, antimicrobial, antiviral, anti-inflammatory and analgesic properties. Objective: Synthesis of new ethyl 2-amino-4-isopropyl-5-methylthiophene-3-carboxylate (2) was used as a starting material to produce 2-mercapto-methylthienopyrimidinone (3), (4) and 2- hydrazinyl-methylthienopyrimidinone (5), through high yields and evaluating anticancer activities. Methods: A series of novel Schiff?s bases (6-9) were produced after treatment of (5) with aldehydes. Triazolopyrimidinones (6a, 7a, 8a, 9a) were produced from cyclization of benzylidene (6-9) using Br2 / AcOH or dry pyridine /Ac2O. Thiazolidinones (6b, 7b, 8b, 9b) were synthesized from benzylidene (6-9) with mercaptoacetic acid. Results: All the compounds were synthesized in good yields (55-85%) in a regularly actual system under mild condition. The new compounds have been established by means of diverse spectroscopic ways as IR, NMR and MS. The newly synthesized compounds were evaluated for their antiproliferative activity against the breast MCF-7 carcinoma cell line. Compound (7) showed promising anticancer activity with IC50 of 6.9 muM, and 40.8% of antioxidant effect as DPPH inhibition. Molecular docking of (7) showed deltaG values of-20.54 kcal/ mol and -25.60 kcal/ mol. Molecular dynamics simulation of (7) in complex with PARP-1 revealed RMSD of 3.00 a. Conclusion: The QSAR study confirmed the presence of a relationship between anticancer activity and subdivided surface area descriptors with coefficient r2 = 0.98 with high predictive power.

There are currently still no approved antiviral drugs to treat or prevent chikungunya virus (CHIKV) infections despite the fact that this arbovirus continues to cause outbreaks in Africa, Asia, and South- and Central-America. Thus 20 new conjugated compounds in the families of bis(benzofuran?1,3-thiazolidin-4-one)s and bis(benzofuran?1,3-thiazinan-4-one)s were designed based on the structural features of suramin. These new compounds were synthesized by chemical methods and their structures were confirmed spectroscopically. In CPE reduction assays, six of these new bis-conjugates inhibited CHIKV replication in Vero E6 cells with EC50 in the range of 1.9?2.7 muM and selectivity index values of ?75 or higher. These results and compounds provide a starting point for further optimization, design, and synthesis of new antiviral agents for this (re)emerging disease.
