Abstract
:
To overcome the upsurge of antimicrobial resistance that has emerged in recent years,
there is a need for the development of newer hits having satisfying anti-infective activity. Hydrazides
incorporated with an azomethine hydrogen account for a cardinal class of molecules for the
development of newer derivatives. Hydrazide derivatives have gained considerable interest of medicinal
chemists owing to their diverse bioactivity. In the present review, we have attempted to
compile the recent trends in the synthesis of hydrazides and their substituted derivatives. The structural
features that lead to the desired antimicrobial activity are highlighted, which will lead the way
for synthetic and medicinal chemists to focus on newer designs in this arena.

Application of NMI-TfCl-mediated amide bond formation in the synthesis of biologically relevant oxadiazole derivatives employing less basic (hetero)aryl amines. Mol Divers 2021; 26:1761-1767.

Abstract
We herein report a modified methodology for the synthesis of some oxadiazoles linked to amides under mild conditions. The developed protocol using NMI-TfCl has been found to be effective and tolerant for the amide bond formation reaction of a series of electronically deactivating and sterically challenging amines. The antioxidant potential of the newly synthesized compounds has been evaluated at the later stage.

Synthesis and fungicidal activity of methyl (E)-1-(2-((E)-2-methoxy-1-(methoxyimino)-2-oxoethyl)benzyl)-2-(1-arylidene)hydrazine-1-carboxylates †‡. Mol Divers 2021; 26:801-813. [PMID: 33548013 DOI: 10.1007/s11030-021-10187-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2020] [Accepted: 01/18/2021] [Indexed: 10/22/2022]
Abstract
To discover novel strobilurin fungicides, a series of methyl (E)-1-(2-((E)-2-methoxy-1-(methoxy-imino)-2-oxoethyl)benzyl)-2-(1-arylidene)hydrazine-1-carboxylates were designed based on the principle of biologically active splicing and the receptor target structure. The fungicidal activity results show that this class of compounds has excellent fungicidal activity, especially against S. sclerotiorum (Lib.) deBary, wheat white powder and puccinia polysora. The result of structure-activity relationship implied that the introduction of t-butyl in the side chain facilitates the hydrophobic interaction between the compound and the active site. The electrostatic effect of the substituents on the benzene ring is also a key factor affecting such activities. Among them, the compound I-1 not only showed a fungicidal effect comparable to that of kresoxim-methyl in vivo, but also had an excellent inhibitory effect on spore germination of P. oryzae Cav in vitro, which indicated that it could be used as a potential commercial fungicide for plant disease control.
