Natural products as a gold mine for arthritis treatment

Arthritis, an inflammation of the joints, is usually a chronic disease that results from dysregulation of pro-inflammatory cytokines (e.g. tumour necrosis factor and interleukin-1b) and pro-inflammatory enzymes that mediate the production of prostaglandins (e.g. cyclooxygenase-2) and leukotrienes
(e.g. lipooxygenase), together with the expression of adhesion molecules and matrix metalloproteinases, and hyperproliferation of synovial fibroblasts. All of these factors are regulated by the activation of the transcription factor nuclear factor-kB. Thus, agents that suppress the expression of tumour necrosis factor-a, interleukin-1b, cyclooxygenase-2, lipooxygenase, matrix metalloproteinases or adhesion molecules, or suppress the activation of NF-kB, all have potential for the treatment of arthritis.

Comparative Evaluation of Solubility and Dissolution Enhancement of Bicalutamide Solid by Dispersion Technique

Bicalutamide is poorly water soluble Anti- Cancer drug used in prostate cancer. Due to poor solubility of drug, its bioavailability rate is limited by drug dissolution. In the present study, an attempt has been made to increase solubility and dissolution of Bicalutamide by solid dispersion technique using Solvent Evaporation and Hot Melt method with PEG- 6000 (Poly ethylene glycol), PVP K-90 (Poly vinyl pyrrolidone), and Poloxamer F-68.

Cyclooxygenase-2 – an Alluring Target for Meaningful Drug Designing

Cyclooxygenase, an enzyme involved in the conversion of C-20 acids to prostaglandins, exists in two isoforms. COX-1 is constitutively expressed and has a gastroprotective function. COX-2, induced at the site of injury, is responsible for the expression of pro-inflammatory prostaglandins. Despite overall similarities, COX-1 and COX-2 show subtle difference in amino acid composition at the active sites. COX-2 has valine at positions 89 and 523, while COX-1 has isoleucine, resulting in larger space availability in the former.
