Synthesis, antimicrobial and antiviral evaluation of substituted imidazole derivatives
摘要:
In the present study, we have synthesized 2-(substituted phenyl)-1H-imidazole (1-12) and (substituted phenyl)-[2-(substituted phenyl)-imidazol-1-yl]-methanone (13-26) analogues and screened them for their antimicrobial activity against Gram positive, Gram negative and fungal species. The results of antibacterial study indicated that compounds 15,17 and 24 showed appreciable antibacterial activity and compound 26 emerged as the most potential antifungal agent. The results of SAR studies indicated that the presence of electron withdrawing groups is necessary for the antimicrobial activity of the synthesized compounds. The results of the present study indicated that compounds 15, 17 and 24 might be of interest for the identification of new antimicrobial molecules as their antibacterial activity is equivalent to the standard drug norfloxacin. Further, the antiviral screening of (substituted phenyl)-[2-(substituted phenyl)-imidazol-1-yl]-methanones (13-26) against a panel of viral strains indicated that compounds 16 and 19 can be selected as lead compounds for the development of novel antiviral agents.

Disubstituted octahydropyrrolo[3,4-c]pyrrole compounds are described, which are useful as orexin receptor modulators. Such compounds may be useful in pharmaceutical compositions and methods for the treatment of diseased states, disorders, and conditions mediated by orexin activity, such as insomnia.

Disubstituted octahydropyrrolo[3,4-c]pyrrole compounds are described, which are useful as orexin receptor modulators. Such compounds may be useful in pharmaceutical compositions and methods for the treatment of diseased states, disorders, and conditions mediated by orexin activity, such as insomnia.
The present invention provide a compound having an orexin receptor antagonistic activity, which is expected to be useful as medicaments such as agents for the prophylaxis or treatment of sleep disorder, depression, anxiety disorder, panic disorder, schizophrenia, drug dependence, Alzheimer's disease and the like.
The present invention relates to a compound represented by the formula (I):
wherein each symbol is as defined in the specification, or a salt thereof.

(DFT), and ion mobility spectrometry-mass spectrometry (IMS-MS) studies. Significant water/alcohol loss was also observed for 1-substituted 1, 2, 3-triazoles but not for the isomeric 2-substituted 1, 2, 3-triazole analogs. IMS-MS, NMR, and DFT studies were conducted to show that the preferred orientation of the 2-substituted triazole rotamer was away from the electrophilic center of the reaction, whereas
