New ursolic acid derivatives bearing 1,2,3-triazole moieties: design, synthesis and anti-inflammatory activity in vitro and in vivo

Abstract: In order to discover novel anti-inflammatory agents, three series of compounds obtained by appending 1,2,3-triazole moieties on ursolic acid were designed and synthesized. All compounds have been screened for their anti-inflammatory activity by using an ear edema model. The potent anti-inflammatory compound was subjected to in vitro cyclooxygenase COX-1/COX-2 inhibition assays. In general, the derivatives were found to be potent anti-inflammatory activity. Especially, the compound 11b exhibited the strongest activity of all of the compounds prepared, with 82.81% inhibition after intraperitoneal administration, which was better than celecoxib as a positive control. Molecular docking results unclose the rationale for the interaction of the compound 11b with COX-2 enzyme. Further studies revealed that compound 11b exhibited effective COX-2 inhibitory activity, with half-maximal inhibitor concentration (IC50) value of 1.16?μM and selectivity index (SI = 64.66) value close to that of celecoxib (IC50 = 0.93?μM, SI = 65.47). Taken together, these results could suggest a promising chemotype for development of new COX-2-targeting anti-inflammatory agent. Graphic abstract: [Figure not available: see fulltext.]

Synthesis and biological evaluation of coumarin-linked 4-anilinomethyl-1,2,3-triazoles as potent inhibitors of carbonic anhydrases ix and xiii involved in tumorigenesis

A series of coumarin-linked 4-anilinomethyl-1,2,3-triazoles (6a–t) was synthesized via a molecular hybridization approach, through carbon C-6 of the coumarin moiety. The synthesized compounds were evaluated for their inhibition of carbonic anhydrase (CA)

Design, synthesis and antibacterial evaluation of novel 1,2,3-triazole derivatives incorporating 3′-deoxythymidine

A series of novel 1,2,3-triazole derivatives incorporating 3′-deoxythymidine were designed, synthesised and characterised. Antibacterial activity against Escherichia coli and Staphylococcus aureus was evaluated for all of the synthesised compounds and com

Anti-methicillin resistant Staphylococcus aureus activity, synergism with oxacillin and molecular docking studies of metronidazole-triazole hybrids

MRSA causes 60-70% of Staphylococcus aureus infection in hospitals and it has developed resistance against the currently available drugs. Interestingly, a series of 35 metronidazole-triazole hybrids on screening against MRSA were found to be active. Compound 22 was found to be effective at 4 μg/mL concentration against nine strains of MRSA. The inhibitory activity was further enhanced upto 1 μg/mL when this compound was used in combination with oxacillin in 1:1 ratio. All the compounds were found to be non-toxic in THP-1 cell line upto a concentration of 50 μM. The time-kill kinetics studies suggested bacteriostatic nature of the compounds. In silico studies show that these compounds interact with Thr600, Ser598, Asn464, His583 and Tyr446 in the active site of PBP2a crystal structure from MRSA.

AgNO2 as the NO Source for the Synthesis of Substituted Pyrazole N-Oxides from N-Propargylamines

A straightforward method for synthesizing the pyrazole N-oxides from N-propargylamines and AgNO2 through oxidation/cyclization reaction had been developed. AgNO2 was used as the NO source for the first time to synthesize pyrazole N-o
