Efficient microwave synthesis of flurbiprofen derivatives and their enhancement of efficacy in chronic inflammatory pain models and gastro-protective potential in post-operative model.

Present research was designed to synthesize and characterize the flurbiprofen derivatives and to evaluate their analgesic, anti-inflammatory and gastro-protective activities in post-operative and chronic inflammatory pain models. Flurbiprofen derivatives were produced by using three-step processes involving esterification, hydrazide production, and schiff base, each of which modified a different carboxyl group. All the newly synthesized flurbiprofen derivatives () were characterized by H NMR,C NMR,F NMR and HR-ESI-MS, and the post-operative, inflammatory pain and ulcerogenic activities were determined in well-established animal models.

Bio-oriented synthesis of ibuprofen derivatives for enhancement efficacy in post-operative and chronic inflammatory pain models.

The discovery of post-operative, chronic inflammatory pain and any gastroulcerogenic potential using well-established animal models with new structures, high efficiency, broad-spectrum, and low toxicity has been the focus of medicinal chemists. In the present article, we are reporting the design and synthesis of various derivatives of ibuprofen by modifying the carboxyl group of ibuprofen using three steps reactions; esterification under microwave-irradiation in 10 minutes, hydrazide formation, and finally schiff's base reaction. Microwave-assisted esterification reaction can be employed to quickly explore and increase molecular diversity in synthetic chemistry.

Background And Objective: Chronic hepatitis, cirrhosis, and hepatocellular carcinoma are mainly caused by hepatitis C infection. It is a worldwide predominant pathogen and is one of the main causes of healthcare problem in Asia. In the last few decades, there has been a considerable change in the treatment regimen for hepatitis C virus.

Evaluation of iron deficiency anaemia for gastrointestinal causes in patients without GI symptoms in high prevalent GI malignancy zones.

Background And Study Aims: Gastric cancer is highly prevalent in Kashmir, as are lower gastrointestinal (LGI) malignancies. Colonic cancer, gastric cancer, and coeliac disease are the most important gastrointestinal (GI) causes of iron deficiency anaemia (IDA) worldwide. Approximately 9% of patients with IDA present with a suspicious lesion in the GI tract upon examination.

Role of the VDR Bsm I and Apa I polymorphisms in the risk of colorectal cancer in Kashmir.

Objective: A case-control study aiming to evaluate the relationship between Bsm I and Apa I restriction fragment gene polymorphisms and colorectal cancer (CRC) was carried out in Kashmir, including a total of 368 subjects (180 cases and 188 controls).

Methods: DNA samples extracted from the blood of the subjects were analyzed for 3' untranslated region (3' UTR) Apa I and Bsm I polymorphisms using restriction fragment length polymorphism-polymerase chain reaction (RFLP-PCR).

Results: A statistically significant 2.

Association of a VDR gene polymorphism with risk of colorectal cancer in Kashmir.

Roles of the vitamin D receptor in etiology of cancers, including colorectal cancer, have been repeatedly stressed in different parts of the world. A case control study aimed to evaluate the relationship between the two was therefore initiated in Kashmir, known both for its increasing incidence of gastrointestinal cancers and deficiency of micro-nutrients especially vitamin D. The study included a total of 617 subjects (312 colorectal cancer cases and 305 controls), with sampling carried out over a period of 5 years.
