Synthesis and Evaluation of New Series of 1,4-Dihydropyridine Derivatives as Anticancer Agents

1,4-dihydropyridine derivatives represent one of the important classes of compounds possessing a wide variety of biological activities including anticancer activity. In the present study, (4-Alkyl/Aryl-1-substituted 2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxilicacid, 3,5-bis [2(aminothioxomethyl)hydrazides]) (6 a-l) were synthesized by the reaction of 4-alkyl/aryl-3,5-dicarboalkoxy-2,6-dimethyl-1,4-dihydropyridines (4 a-l) with thisemicarbazide and evaluated for their anti-cancer properties. All the synthesized compounds were characterized by IR, NMR and Mass spectra and were screened to evaluating for anticancer activity against three cell lines (MCF-7, HeLa and Hep G2) by using MTT assay method. The results showed that compounds 6j and 6l showed significant cytotoxicity with IC50 values ranging from 5

Benzimidazole: Pharmacological Profile

Benzimidazole is a bicyclic heterocyclic aromatic compound in which benzene fused to imidazole moiety. Benzimidazole holds a vital role in the field of medicinal chemistry which possesses wide variety of pharmacological activities like antibacterial, anti cancer, antifungal, antileishmanial, anti tubercular, anti viral and anti malarial respectively, hence the benzimidazole moiety attracting the medicinal chemist to synthesize the different benzimidazole derivatives with wide variety of pharmacological activities. The book chapter mainly discussed the anti cancer, anti HIV, antileishmanial and anti tubercular activites of recently synthesized benzimidazole derivatives

Design and invitro evaluation of gastro retentive oral matrix tablet formulations of ketorolac tromethamine

Ketorolac Tromethamine floating tablets were prepared by using combination of hydrophilic polymers such as Hydroxy Propyl Methyl Cellulose 4000 cps grade and 100000 cps grade. Eight set of formulations were prepared by gradual increasing and decreasing concentrations of above two polymers. The floating pattern was found to be instant for all the formulations and best controlled release profile was achieved for few set of formulations. The drug content, tablet weight, friability and weight variation were found to be within the limits. Validated UV spectrophotometric method was developed and standard linear regression was used to determine the concentration of released drug during the course of dissolution. The release studies were subjected to zero order, first order, higuchi and ritger-peppas kinetics and the parameters for controlled release were calculated

TRANSDERMAL PATCHES FOR THE TREATMENT OF ANGINA PECTORIS: AN EFFECTIVE DRUG DELIVERY SYSTEM-A REVIEW

Topical delivery methods have been used since the dawn of time, employed to cure a wide range of ailments and for aesthetic purposes. Transdermal drug delivery has evolved throughout time, with the development of passive and active technologies that have resulted in enhanced distribution, accuracy in drug dosage, and better fulfilment of the requirements of the individual. The search for more powerful pharmaceuticals that can be delivered to the skin through appropriate transdermal technologies will continue to be a focus in the development of drugs for transdermal patches and other forms of delivery. Topical and transdermal distribution has been around for a while, but this review will focus on transdermal patches and how they've evolved. The articles have been searched on different search engines such as Scopus database, Science direct, PubMed, Google scholar, and Bentham science using multiple keywords. An adhesive transdermal patch is applied to the skin and contains medicine that is absorbed into the bloodstream through the skin. It aids in the recovery of an afflicted part of the body. When compared to oral, topical, i. v., and i. m. administration systems, transdermal drug delivery allows a controlled release of the medicine into patients, often by either a porous membrane or by body heat melting small layers of medication embedded in the adhesive. The fundamental drawback of transdermal delivery methods is that the skin is a highly efficient barrier, therefore, only tiny molecules can enter the skin and be administered in this manner

Dengue fever occurrence in India, Brazil, Paraguay, Philippines and Singapore using Google trends

Background. Dengue is a mosquito-borne disease and its occurrence is a worldwide problem. The health seekers may turn to the Internet based data for possible complications and various therapeutic approaches for the treatment. Therefore, our objective is to identify and characterize the seasonal transition of dengue fever using Google Trends. Methods. This was a cross-sectional study of dengue fever internet searches between 2004 and 2017. The Google was indexed the aggregated web data and ranked based on the search volume with respect to time. The countries selected for the study include India, Brazil, Paraguay, Philippines and Singapore based on the maximum number of cases across world. The selected regions were further classified in to seasonal time points and the relative search volume ranks were categorized to two season variables. Mann–Whitney U test was applied to identify the statistical significance. Results. The summer to monsoon transitions were showed highest number cases beginning from 2004 in the selected regions. Furthermore, dengue searches were peaked in both the seasons of summer and monsoon in selected regions. The analyses of data further revealed that 16.2 % of variation in dengue trends is associated with the time between 2004 and 2017
