Objective: Some new imidazole derivatives (3i-xii) were synthesized as per design synthetic protocol scheme. The structures of newly prepared compounds were confirmed by modern analytical technique and elemental analysis.

Methods: All the synthetic compounds were screened for their antimicrobial activity against bacterial results showed good to remarkable activity. The MIC (minimum inhibitory concentration) values were determined by comparison to ciprofloxacin (anti-bacterial) and fluconazole (anti-fungal) as standard drug. Among them, compound 3iv and 3x exhibited notable antimicrobial activity. These compounds may be used as new template for the searching of potential antimicrobial agents.

Results: The purity of the compound was verified with the help of TLC (B: A, 9:1). % age of yield was found 83% and melting point noted 151-1520C. Compounds (3ii, 3viii and 3ix) were shown moderate activity against E. coli, S. aureus, M. luteus and K. pneumonia, whereas compounds (3iii, 3vii, 3xi and 3xii) showed mild activity against few bacterial strainsμg/ml.  The compounds of electron releasing imidazole derivatives (3ii, 3iv, 3viii, 3ix, 3x and xi) presented comparatively better anti-fungal activity than the compounds of electron withdrawing imidazole derivatives (3iii, 3vii and 3xii).

Conclusion: The biological activity result revealed that all the newly synthetic compounds 3i-xii [4-(biphenyl-4-yl)-2-(substituted phenyl)-1H-imidazole] exhibited better antibacterial activity as compared to antifungal activity in compare to reference drug.

UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system. The identity of the authors and, reviewers will be known to each other. This transparent process will help to eradicate any possible malicious/purposeful interference by any person (publishing staff, reviewer, editor, author, etc) during peer review. As a result of this unique system, all reviewers will get their due recognition and respect, once their names are published in the papers. We expect that, by publishing peer review reports with published papers, will be helpful to many authors for drafting their article according to the specifications. Auhors will remove any error of their article and they will improve their article(s) according to the previous reports displayed with published article(s). The main purpose of it is ‘to improve the quality of a candidate manuscript’. Our reviewers check the ‘strength and weakness of a manuscript honestly’. There will increase in the perfection, and transparency.
