Abstract
A series of novel 6-sulfonyl-1,2,4-triazolo[3,4-b][1,3,4]thiadiazole derivatives were designed and synthesized. CoMFA models were established to analyze the quantitative structure-activity relationships on the basis of the EC50 values of the compounds. The models were used to design and synthesize compounds 32 and 33 with higher activities. The EC50 values of compound 33 against Xanthomonas oryzae pv. oryzae (Xoo) and Xanthomonas oryzae pv. oryzicola (Xoc) were 0.59 and 1.63 mg/L, respectively, which were higher than those of thiodiazole copper (90.43 and 97.93 mg/L) and bismerthiazol (68.37 and 75.59 mg/L). Moreover, protective activities of compound 33 against bacterial leaf streak (BLS) and bacterial leaf blight (BLB) were 49.65% and 49.42%, respectively, which were superior to those of thiodiazole copper (44.28% and 41.51%) and bismerthiazol (38.89% and 40.09%). Protective activity of compound 33 against BLS was closely related to the improvement of defense-related enzyme activities, chlorophyll content, and photosynthesis activation. This is consistent with the upregulated expression of defense responses and photosynthesis-related proteins.

POCl3 Mediated Syntheses, Pharmacological Evaluation and Molecular Docking Studies of Some Novel Benzofused Thiazole Derivatives as a Potential Antioxidant and Anti-inflammatory Agents. ACTA ACUST UNITED AC 2020. [DOI: 10.2174/2212796813666191118100520] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 01/31/2023]
Abstract
Background:
The present research work is focused on the development of alternative
antioxidant and anti-inflammatory agents. The review of the literature reveals that many
benzofused thiazole analogues have been used as lead molecules for the design and development
of therapeutic agent, including anticancer, anti-inflammatory, antioxidant and antiviral.
The synthesized benzofused thiazole derivatives are evaluated for in vitro antioxidant,
anti-inflammatory activities and molecular docking study. Thus, the present research work
aims to synthesize benzofused thiazole derivatives and to test their antioxidant and antiinflammatory
activities.
Objective:
To design and synthesize an alternative antioxidant and anti-inflammatory agents.
Methods:
The substituted benzofused thiazoles 3a-g were prepared by cyclocondensation reaction
of appropriate carboxylic acid with 2-aminothiophenol in POCl3 and heated for about
2-3 h to offer benzofused thiazole derivatives 3a-g. All the newly synthesized compounds
were in vitro screened for their anti-inflammatory and antioxidant activities by using a
known literature method.
Results:
At the outset, the study of in vitro indicated that the compounds code 3c, 3d and 3e
possessed distinct anti-inflammatory activity as compared to a standard reference. All the
tested compounds show potential antioxidant activity against one or more reactive (H2O2,
DPPH, SO and NO) radical scavenging species. Additionally, docking simulation is further
performed to the position of compounds 3d & 3e into the anti-inflammatory active site to determine
the probable binding model.
Conclusion:
New anti-inflammatory and antioxidant agents were needed; it has been proved
that benzofused thiazole derivatives were 3c, 3d and 3e constituted as an interesting template
for the evaluation of new anti-inflammatory agents and an antioxidant’s work also may provide
an interesting template for further development.

Abstract
Antibiotics are commonly used to fight against bacterial infections, but bacteria have already been resistant to almost all antibiotics due to abuse of antibiotics. 1,2,4-Triazole derived compounds possess chemotherapeutic effects including potential antibacterial activities against drug-sensitive as well as drug-resistant pathogens. Hybridization displays a high potential to develop novel drugs with the capacity to overcome drug resistance, reduce toxicity and improve pharmacokinetic profiles. More effective antibacterial candidates might be obtained by the hybridization of 1,2,4-triazole with other antibacterial pharmacophores. This review summarizes the recent advances of 1,2,4-triazole derivatives as potential antibacterial compounds, and the structure-activity relationship is also discussed.
