An in silico approach was adopted to identify potential cyclooxygenase‐2 inhibitors through molecular docking studies. The in vivo studies indicated that synthetic palmitoyl derivatives of salicylic acid, para amino phenol, para amino benzoic acid, and anthranilic acid possessed significant pharmacological activities like anti‐inflammatory, analgesic, and antipyretic activities. None of the tested substances produced any significant gastric lesions in experimental animals. In an attempt to understand the ligand–protein interactions in terms of the binding affinity, the above synthetic molecules were subjected to docking analysis using AutoDock. The palmitoyl derivatives palmitoyl anthranilic acid, palmitoyl para amino benzoic acid, palmitoyl para amino phenol, and palmitoyl salicylic acid showed better binding energy than the known inhibitor diclofenac bound to 1PXX. All the palmitoyl derivatives made similar interactions with the binding site residues of cyclooxygenase‐2 as compared to that of the known inhibitor. Thus, structure‐based drug discovery approach was successfully employed to identify some promising pro‐drugs for the treatment of pain and inflammation.
Molecular docking studies of four synthesized compounds on COX‐2 protein using AutoDock proved to be successful in identifying them as promising lead compounds for the treatment of pain, fever and inflammation.

Cancer risks for MLH1 and MSH2 mutation carriers
ABSTRACT We studied 17,576 members of 166 MLH1 and 224 MSH2 mutation‐carrying families from the Colon Cancer Family Registry. Average cumulative risks of colorectal cancer (CRC), endometrial cancer (EC) and other cancers for carriers were estimated using modified segregation analysis co ... more
Scope Flavonoids have well‐known antioxidant, anti‐inflammatory, and anti‐cancer activities. Isoflavone genistein is considered a potent antioxidant agent against oxidative stress. Although several mechanisms have been proposed, a clear antioxidant mechanism of genistein is still remain ... more
Abstract People can get oral cancers from UV (290‐400 nm) exposures. Besides high outdoor UV exposures, high indoor UV exposures to oral tissues can occur when consumers use UV‐emitting tanning devices to either tan or whiten their teeth. We compared the carcinogenic risks of skin to or ... more
Marijuana use may increase risk of testicular cancer
A new study from the University of Southern California (USC) has found a link between recreational marijuana use and an increased risk of developing subtypes of testicular cancer that tend to carry a somewhat worse prognosis. Published in CANCER the findings suggest that the potential cance ... more
New Study into Bladder Regeneration Heralds Organ Replacement Treatment
Researchers in the United States have developed a medical model for regenerating bladders using stem cells harvested from a patient’s own bone marrow. The research, published in STEM CELLS, is especially relevant for paediatric patients suffering from abnormally developed bladders, but also ... more
Stem Cells journal awards human cord-blood research
The journal Stem Cells has announced Dr. Cinzia Rota as the winner of the annual Stem Cells Young Investigator Award. Co-sponsored by the International Stem Cell Symposium, the $10,000 prize is annually given to a young scientist who is the principal author of a research paper published in ... more
