WebThe specific optical rotation, [a]~ ' of a solid substance is the angle of rotation, 'a', of the plane of polarisation at the wavelength of the D line of sodium (A. = 589.3 nm) measured at 25°, unless otherwise specified, calculated with reference to a 1-dm thick layer of a solution containing 1 g of the substance per ml. WebThe optical rotation of a number of pure pharmaceutical substances may be measured accurately by noting the angle through which the plane of polarization is rotated when polarized light passes through the substance, if liquid or through a solution of the substance, if solid. A few typical examples of ibuprofen and levodopa are discussed below :

Optical resolution can be … WebIbuprofen is a non-selective inhibitor of cyclooxygenase, an enzyme invovled in prostaglandin synthesis via the arachidonic acid pathway. Its pharmacological effects are believed to be due to inhibition cylooxygenase-2 (COX-2) which decreases the synthesis of prostaglandins involved in mediating inflammation, pain, fever and swelling. fivem paleto bay dealership
