Pedrood, Keyvan;Azizian, Homa;Montazer, Mohammad Nazari;Mohammadi-Khanaposhtani, Maryam;Asgari, Mohammad Sadegh;Asadi, Mehdi;Bahadorikhalili, Saeed;Rastegar, Hossein;Larijani, Bagher;Amanlou, Massoud;Mahdavi, Mohammad research published 《 Arylmethylene hydrazine derivatives containing 1,3-dimethylbarbituric moiety as novel urease inhibitors》, the research content is summarized as follows. A new series of arylmethylene hydrazine derivatives bearing 1,3-dimethylbarbituric moiety I (Ar = Ph, 2,3-dichlorophenyl, naphthalen-1-yl, thiophen-2-yl, etc.) was designed, synthesized, and evaluated for their in vitro urease inhibitory activity. All the title compounds I displayed high anti-urease activity, with IC₅₀ values in the range of 0.61 ± 0.06-4.56 ± 0.18μM as compared to the two standard inhibitors hydroxyurea (IC₅₀ = 100 ± 0.15μM) and thiourea (IC₅₀ = 23 ± 1.7μM). Among the synthesized compounds I, compound I (Ar = 2-nitrophenyl) with 2-nitro benzylidene group was found to be the most potent compound Kinetic study of this above compound revealed that it is a mix-mode inhibitor against urease. Evaluation of the interaction modes of the synthesized compounds in urease active site by mol. modeling revealed that that compounds with higher urease inhibitor activity (I (Ar = 2-nitrophenyl, thiophen-2-yl, 2,4-dihydroxyphenyl, 5-chloro-2-nitrophenyl, 4-nitrophenyl and naphthalen-1-yl), with IC₅₀ of 0.61, 0.86, 1.2, 1.34, 1.33, 1.94μM, resp.) could interact with higher number of residues, specially Arg609, Cys592 (as part of urease active site flap) and showed higher computed free energy, while compounds with lower urease activity (I (Ar = 4-chlorophenyl, 5-chlorothiophen-2-yl, 3-bromophenyl and Ph) with IC₅₀ of 3.56, 4.56, 3.62 and 4.43μM, resp.) and could not provide the proper interaction with Arg609, and Cys592 as the key interacting residues along with lower free binding energy. MD investigation revealed that compound I (Ar = 2-nitrophenyl) interacted with Arg609 and Cys592 which are of the key residues at the root part of mobile flap covering the active site. Interaction with the mentioned residue for a significant amount of time affects the flexibility of the mobile flap covering the active site and causes inhibition of the ureolytic activity. Furthermore, in silico physico-chem. study of compounds I predicted that all these compounds are drug-likeness with considerable orally availability.

Park, So Hee;Choi, Dubok;Cho, Hoon research published 《 Effect of thiazolidinedione phenylacetate derivatives on wound-healing activity》, the research content is summarized as follows. The aim of this work was to evaluate the synthesis and structure-activity relationship of 4-((2,4-dioxothiazolidin-5-ylidene)methyl)phenyl 2-phenylacetate derivatives as potential wound-healing agents. The IC₅₀ values of the lead compounds ranged from 0.01 to 0.05 μM. These compounds also increased the levels of extracellular prostaglandin E₂ (PGE₂) in A549 cells. Among the synthesized compounds, compounds 66, 67, 69, and 86 increased PGE₂ levels 3- to 4-fold of those achieved with the neg. control. Introduction of a halogen at the intermediate Ph ring, compounds 66, 67, 69, and 86 resulted in higher IC₅₀ values, which indicated lower cytotoxicity than that observed upon the introduction of other substituents at the same position. In particular, cells exposed to compound 69 showed significantly improved wound healing, and the wound closure rate achieved was approx. 3.2-fold higher than that of the control. Therefore, compound 69 can be used for tissue regeneration and treatment of diverse diseases caused by PGE₂ deficiency.
