Chronic obstructive pulmonary disease (COPD) is characterised by an abnormal inflammatory response of the lung to noxious particles or gases. The cellular inflammatory response in COPD is characterised by an increased number of inflammatory cells in the lungs. Although the molecular and cellular mechanisms responsible for the development of COPD are not well understood; several mediators are assumed to regulate Read More

Cyclooxygenase (COX) enzyme is responsible for the formation of important biological mediators including prostaglandins, prostacyclin and thromboxane to trigger many physiological and patho-physiological responses. COXs exist in two distinct isoforms, a constitutively expressed form (COX-1) and an inducible form (COX-2). COX-2 is involved in the body’s response to inflammation and pain. Moreover, it has also been sh Read More

Isoniazid (INH) is one of the most commonly used drugs in treatment of human tuberculosis and the most efficient. Although it has been 60 years since isoniazid was introduced in anti-tubercular therapy and despite the simplicity of its chemical structure (C6H7N3O) with few functional groups, its exact mechanism of action, which could account for its specificity and exceptional potency against Mycobacterium tuberculosis and j Read More

Quinoline-based small molecules have been explored and being developed as anti-inflammatory agents targeting several pharmacological targets namely Phosphodiesterase 4 (PDE4), Transient Receptor Potential Vanilloid 1 (TRPV1), TNF-α converting enzyme (TACE) and Cyclooxygenase (COX). Efforts on Structure Activity Relationship (SAR) studies revealed that the pharmacological activities and target specificities of these quino Read More

Reduced function of the thyroid gland causes Hypothyroidism which is further attributed to defects in the secretion of thyroid hormones triiodothyronine (T3) and tetra-iodothyronine or thyroxine (T4). T3 and T4 hormones are not only known to regulate the rate of metabolism but also affect the growth and rate of function of many other systems in the body such as neuromuscular, gastrointestinal and cardiovascular sy Read More

Phosphatidylcholine-polymer-coated plastic slides were utilized for the fabrication of peptide microarrays for cellular kinome analysis. According to the non-fouling features of the surface, the signal-to-noise ratio of the detection of phosphorylated peptides improved by about 100-fold from that of a peptide microarray fabricated on a glass slide blocked by a commercial BSA-based reagent. When the phosphatidylcholine-polymer Read More

This study was designed to investigate the molecular effects of diphenyl diselenide ((PhSe)2) on cholesterol metabolism in HepG2 cell line in a dose-dependent manner. The protein levels of both total and phosphorylated 3- hydroxy-3-methylglutaryl coenzyme A reductase (HMGR and P-HMGR), low-density lipoprotein receptors (LDLr) and the proteins involved in their regulatory network were analyzed by Western blotting, and th Read More
