Opis:
In this study some new o-benzimidazol-2'-yl-benzamido-p'-benzamido-2-phenyl-4-substituted phenyl-5-oxo-Imidazolines 3a-3j were synthesized. To synthesized target molecules we used various substituted oxazolone derivatives, synthesized from substituted benzaldehyde with hippuric acid. Substituted oxazolones 2a-2j were reacted with carbohydrazide derivative of benzimidazole 1 in presence of pyridine as base to obtained substituted imidazolinone derivatives. All synthesized compounds were characterized by IR, 1H NMR, elemental analysis and further supported by mass spectroscopy. All synthesized compounds were screened for their antimicrobial activity against gram positive and gram negative bacteria which showed moderate to good activity. All compounds showing good to moderate active against fungal strain as compare to standard drug.

Opis:
InWO3 -TiO2 nanocomposite material was synthesised by co-precipitation method and sonication technique. The synthesized nanomaterial was characterized by FE-SEM with EDX, HR-TEM, XRD, FT-RAMAN, AFM and BET surface area measurements. The photocatalytic activity of InWO3-TiO2 nanocomposite material was studied from the photodegradation of malachite green (MAG) under UV-light irradiation. The photodegradation of MAG at various parameters are reported. The Photodegradation was found to follow the pseudo-first-order kinetics. The Hydroxyl radical formation in the mechanism was confirmed by fluorescence quenching technique. The antimicrobial activity of the prepared nanomaterials has also been investigated. Cyclic voltammeter (CV)) measurements analysis of the prepared nonamaterial was discussed in detail. It was proposed that the catalyst was found to be stable and reusable.

Opis:
The synthesis of a novel xanthene derivatives bearing dimedone as an excellent precursor has been achieved by applying one pot three component Hantzsch type condensation. The newly synthesized compounds were characterized by spectral and elemental analyses. All synthesized compounds undergo docking studies and biological screening for antimicrobial activity against Gram-positive bacteria, Gram-negative bacteria and fungal species. Among all the tested compounds, it was found that compound 3c, 3d, 3g and 3h revealed better activities against the Gram-positive rather than the Gram-negative bacteria whereas results of docking studies revealed that compounds 3b, 3g and 3i showed best binding affinity towards ATP binding pocket of Human PIM1 kinase receptor through steric favorable and H-bond interactions.

These coumarin chalcones 3a-f were then employed for the synthesis of pyrazolyl bipyridinyl substituted coumarins 7a-f, 8a-f, and 9a-f under Krohnke’s reaction condition. The characterization of all the synthesized compounds was carried out by elemental analysis, IR, 1H-NMR, 13C-NMR, DEPT-135 and mass spectral analysis. In addition to that, in vitro antimicrobial competency of the title compounds was assessed against selected pathogens. Compounds 3b, 3e, 7b, 8b, 8c and 9b exhibited excellent antimicrobial activity and said to be the most proficient members of the series.

Many of the plant materials, from which natural dyes are obtained, found to have some medicinal values. During the present study, dying materials were prepared from barks of Terminalia arjuna. The well diffusion method was adopted to examine antimicrobial activity of dying material against test organisms. The result showed that the dying material of Terminalia arjuna was most active for antibacterial (8 mm) and antifungal (7 mm). Results of the present study suggest that the dying material of Terminalia arjuna has significant antibacterial activity against pathogenic bacteria and fungus.

Opis:
Finding healing power in plants is an ancient idea, and people of all continents and civilization have been using plants in one form or the other for poultices or as decoctions. Alangium salvifolium (Linn), family Alangeaceae, is a tree that grows in the wild throughout India. The plant has been used in the Indian traditional system of medicine for skin diseases (e.g. leucoderma), articular diseases, and anti-inflammation, anti-poisonous, anti-pyretic, and anti-emetic requirements. However, no scientific evidence is available regarding its antimicrobial activity. An investigation of Alangium salvifolium as an antimicrobial activity agent is the objective of our present study. The ATCC culture used in this study was collected from department of Microbiology, G.M.C., Bhopal (M.P.). Shade dried crude powder (200 grams) of seed of Alangium salvifolium was separately extracted with methanol in a soxhelt apparatus. The Antimicrobial activities were then studied by applying the Disc–Diffusion method. Our results indicate that the observed antimicrobial activity of the fraction appears to be due to unknown secondary metabolites in it. H.P.L.C. (high performance liquid chromatography) and chemical studies may, thus be useful in analyzing the presence of unknown secondary metabolites in the fractions.
