Design, Synthesis, Safener Activity, and Molecular Docking of Novel N ‐Substituted Thiazide/Thiazole Derivatives

Herbicide Safeners: From Molecular Structure Design to Safener Activity

Herbicide safeners, highly effective antidotes, find widespread application in fields for alleviating the phytotoxicity of herbicides to crops. Designing new herbicide safeners remains a notable issue in pesticide research. This review focuses on discussing and summarizing the structure-activity relationships, molecular structures, physicochemical properties, and molecular docking of herbicide safeners in order to explore how different structures affect the safener activities of target compounds. It also provides insights into the application prospects of computer-aided drug design for designing and synthesizing new safeners in the future.

Research Progress in the Design and Synthesis of Herbicide Safeners: A Review

Detoxification plays an important role in herbicide action. Herbicide safeners selectively protect crops from herbicide injury without reducing the herbicidal efficiency against the target weeds. With the large-scale use of herbicides, herbicide safeners have been widely used in sorghum, wheat, rice, corn, and other crops. In recent years, an increasing number of unexpected new herbicide safeners have been designed. The varieties, structural characteristics, uses, and synthetic routes of commercial herbicide safeners are reviewed in this paper. The design ideas and structural characteristics of novel herbicide safeners are summarized, which provide a basis for the design of bioactive molecules as new herbicide safeners in the future.

Synthesis, In silico and Biological Studies of Thiazolyl-2h-chromen-2-one Derivatives as Potent Antitubercular Agents

BACKGROUND

A series of new six thiazolyl-2-amine-based Schiff base derivatives (4a-4f) were synthesized by a sequential multistep reaction starting with Salicylaldehyde.

METHODS

All the Schiff base derivatives were screened in-vitro for their antibacterial activity against Mycobacterium tuberculosis (H37RV strain) ATCC No-27294. The synthesized compounds were characterized by FTIR, 1H-NMR, 13C-NMR and Mass spectrometry.

RESULTS

Among the compounds tested, 4c and 4f derivatives exhibited potent antitubercular activity against M. tuberculosis at MIC 6.25 μg/mL.

CONCLUSION

We extended our study to explore the inhibition mechanism by conducting molecular docking analysis by using Schrodinger's molecular modeling software. All the newly synthesized compounds were found to be in-silico AMES test non-toxic and non-carcinogens. The good Qikprop's Absorption, Distribution, Metabolism and Excretion (ADMET) would definitely help the researchers in order to make more potent Anti-TB agents.
