Sulfonamide derivatives are frequently seen structural motifs in medicinal chemistry. Almost a century after Gerhard Domagk’s pioneering work leading to the first sulfonamide antibiotic Prontosil, sulfa-drugs are still widely utilized in various pharmaceutical applications due to their antibacterial, antiviral, antimalarial, antifungal, anticancer, antidepressant, or other properties. In the past few years, the interest in sulfonamides has increased as their broad range of bioactivity and versatile structure make them excellent candidates for repurposing old drugs or developing new multi-target agents in the emerging field of polypharmacology. This digest aims to provide an overview of recent advances in sulfonamide-based bioactive compounds, their importance in drug discovery and development emphasizing multi-target approaches for complex diseases, and their novel contribution to contemporary medicinal chemistry.

In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 288-14-2, name is Isoxazole, introducing its new discovery. Formula: C3H3NO

Benzothiazole (BTA) and its derivatives are the most important heterocyclic compounds, which are common and integral feature of a variety of natural products and pharmaceutical agents. BTA shows a variety of pharmacological properties, and its analogs offer a high degree of structural diversity that has proven useful for the search of new therapeutic agents. The broad spectrum of pharmacological activity in individual BTA derivative indicates that, this series of compounds is of an undoubted interest. The related research and developments in BTA-based medicinal chemistry have become a rapidly developing and increasingly active topic. Particularly, numerous BTA-based compounds as clinical drugs have been extensively used in practice to treat various types of diseases with high therapeutic potency. This work systematically gives a comprehensive review in current developments of BTA-based compounds in the whole range of medicinal chemistry as anticancer, antibacterial, antifungal, antiinflammatory, analgesic, anti-HIV, antioxidant, anticonvulsant, antitubercular, antidiabetic, antileishmanial, antihistaminic, antimalarial and other medicinal agents. It is believed that, this review article is helpful for new thoughts in the quest for rational designs of more active and less toxic BTA-based drugs, as well as more effective diagnostic agents and pathologic probes.

A plethora of selective COX-2 inhibitors belonging to nine chemical classes (pyrrole, imidazole, cyclopentene, benzene, pyrazole, spiroheptene, spiroheptadiene, isoxazole, and thiophene) was subjected to quantitative structure-activity relationship (QSAR) analysis using semi-empirical (AM1)-computed quantum mechanical properties and electrotopological state (E-state) indices. These computed parameters were correlated with experimental inhibitory activities (pIC50). Multilinear regression analyses produced three statistically acceptable models. Model 1 is based on quantum mechanical properties only, Model 2 is an all-E-state relationship, and Model 3 embraces both quantum mechanical and electrotopological parameters. All three models surpassed the commonly allowed minimum predictive squared correlation coefficient (q2) of 0.60. These QSAR results and the probable pharmacophore features identified in this study offer important structural insight into designing novel anti-inflammatory drugs devoid of unwelcome side effects. Guided by the generated models, 18 chemical structures belonging to spiroalkene classes were designed with calculated pIC50 values higher than that of known potent COX-2 inhibitors.

The kinetic study on the hydrolysis of Schiff bases (SBs) 1a-c and 2a-c induced by UV-vis was undertaken as a complementary study of the stability in solution and in bulk of the SBs. Solutions in chloroform were exposed to UV-vis and acquisition data occurred for 1a-c and for 2a-c in 21C, 30 C, 35C and 40C. Kinetic profile for 1a-c and 2a-c displayed the similar photochemical behaviour in that four temperature values. At 21C, two kinetic regimes were observed where the decomposition of SBs is faster at the initial stage, with no linear plot of absorbance vs time, and after the kinetic profile obeyed a linear behaviour. A mathematical treatment of the experimental data was applied, which allowed associating the initial stage data with a second-order reaction, and the final stage of the hydrolysis with a first-order reaction. The mechanism of photochemical hydrolysis of SBs 1a and 2a was addressed. It was composed of three parts, the excitation, then the isomerisation and activation processes of tetrahedral intermediate and, the last process, a collapse of the intermediate to the yielded products of the hydrolysis aldehydes and amines which were detected by their UV-vis spectrum.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application In Synthesis of Isoxazole, you can also check out more blogs about288-14-2

For the first time combretastatins were isolated from African willow tree Combretum Caffrum. Subsequent studies have shown the impact of combretastatin A4 phosphate, a water-soluble prodrug, on endothelial cells in tumor vascular system. The same effect was not observed in the vascular system. This selectivity is associated with combretastatins mechanism of action: binding to colchicine domain of microtubules, which affects the cytoskeleton functionality of immature endothelial cells. At the same time, combretastatins directly induce cell death via apoptosis and/or mitotic catastrophe pathways. The combination of both elements makes combretastatin an anticancer compound of high efficiency. The cis-configuration is crucial for its biological activity. To date, many derivatives were synthesized. The attempts to resolve spontaneous isomerization to less active trans-stilbene derivative are still in progress. This issue seems to be overcome by incorporation of the ethene bridge with heterocyclic moiety in combretastatins structure. This modification retains the cis-configuration and prevents isomerization. Nevertheless, combretastatin A4 phosphate disodium is still the most potent compound of this group. The combination therapy, which is the most effective treatment, includes combretastatin A4 phosphate (CA4P) and conventional chemotherapeutics and/or radiotherapy. CA4P is relatively well tolerated giving adverse events of moderate severity, which includes: nausea, vomiting, headache, and tumor pain. The aforementioned effects subside on the day of drug administration or on the following day.
