diosmin and hesperidin are natural flavonoid glycosides found in various plant materials, mainly in citrus fruits in different concentrations. diosmin for pharmaceutical use is obtained mainly semi-synthetically from hesperidin. hesperidin often accompanies diosmin as a natural impurity in different pharmaceutical formulations; therefore, a simple, fast and precise method for the simultaneous a...
The research process for new drug is complicated, time-consuming, and costly. Thousands of chemical compounds must be made and tested in an effort to find one that can achieve a desirable result. It may take approximately ten years to study and test a new drug before it can be approved for the general public. However, in today's pharmaceutical industry drug delivery has become keys in drug prod...
Pharmaceutical wastewaters are generated through complex manufacturing processes that contain a variety of organic and inorganic constituents, and are usually characterized by a high concentration of chemical oxygen demand (COD), suspended solids, dissolved solids (salts), toxicity, and refractory compounds. Therefore, it must be treated. The treatment of a pharmaceutical wastewater (PWW) using...
Bivalves are a class of marine mollusks with high nutritional value in addition to various medicinal products. The Persian Gulf is home to 224 species from 29 families of bivalves identified so far. Based on research conducted in the Persian Gulf or other parts of the world, bioactive compounds exist in their shell and soft tissue. In this review article, we reviewed biomedical research related...
The application of terahertz pulsed spectroscopy to polymorphic, liquid crystalline and amorphous forms of pharmaceutical compounds has been investigated. The different polymorphic forms of carbamazepine and enalapril maleate exhibit distinct terahertz absorbance spectra. In contrast to crystalline indomethacin and fenoprofen calcium, amorphous indomethacin and liquid crystalline fenoprofen cal...
1 Department of Pharmaceutical Sciences, Singhania University, Jhujhunu-333515, Rajasthan, India. 2 National Institute of Pharmaceutical Education & Research, Raebareli229010, Uttar Pradesh, India. A b s t r a c t Starting from different ketones 1a-1f, aldehyde 2a-2g, and acetonitriles 3a-3d we synthesize some bioactive βAcetamido carbonyl compounds 4a-4h. We also attempted to synthesize these ...
Psychotropic drugs are an important family of compounds from a medical point of view. Their application in therapy requires methods for the determination in pharmaceutical dosage forms and body fluids. Several methods for their analysis have been reported in the literature. Among the methods, spectrophotometric and electrochemical are very useful for the determination of the drugs. Some of the ...
