Indole derivatives (Isatin) are potential synthons, for building synthetically a variety of chemical systems known for their broader biological and pharmacological applications. In the present investigation, title compounds (V1-V5) were synthesized by the condensation reaction of 3-[(2)-(phenyl methylidene) hydrazono]-1, 3-dihydro-2H-benzo[g]indol-2-one (IV) with different aryl aldehydes, as such reactions are not reported so far. The synthesized compounds were characterized by IR, 1H NMR and MASS spectroscopy. They were screened for their antimicrobial potential against bacterial strains i.e., Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Proteus vulgaris and fungal strains i.e., Candida albicans and Yeast. Compound V5 (Nitro) was more potent anti- microbial agent against both bacteria [Gram (+Ve) and Gram (-Ve) organisms] followed by compound V4 (Chloro) and V2 (4-Methoxy).Keywords

The primary purpose of the present study is to obtain a true insight into the operating performance of the selected cement companies in India. However the specific objective of the study is to analyze the trends of production, capacity utilization, sales and market share of selected companies of Indian cement industry. It is observed that all the selected companies revealed fluctuating trend of production, capacity utilization and market share during the study period. The projection of production of cement in India showed that all the selected companies have growing good market potential in our country. Chettinad Cement Corporation Limited, Shree Cement Limited, Dalmia Cement Limited and Birla Corporation Limited also showed better performance with regard to their capacity utilization. The sales of all the selected companies marked a rising trend throughout the study period. The projection of sales of cement in India revealed that Grasim Industries Limited and Associated Cement Companies Limited have a fast emerging, growing market in the years to come in India. The analysis of company wise dispersion in market shares of Indian cement industry revealed that the mean rates of market share vary greatly in the case of all the companies.
