An Alternative Medical Diagnosis Method: Biosensors For Virus Detection
(2019)Infectious diseases still pose an omnipresent threat to global and public health, especially in many countries and rural areas of cities. Underlying reasons of such serious maladies can be summarized as the paucity of ... -
An Anomalous Addition Of Chlorosulfonyl Isocyanate To A Carbonyl Group: The Synthesis Of ((3As,7Ar,E)-2-Ethyl-3-Oxo-2,3,3A,4,7,7A-Hexahydro-1H-Isoindol-1-Ylidene)Sulfamoyl Chloride
(2019)In this study, we developed a new addition reaction of chlorosulfonyl isocyanate (CSI), starting from 2-ethyl-3a,4,7,7a-tetrahydro-1H-isoindole-1,3(2H)-dione. The addition reaction of CSI with 2-ethyl-3a,4,7,7a-tetrahydr ... -
An Anticancer C-Kit Kinase Inhibitor Is Reengineered To Make It More Active And Less Cardiotoxic
(Amer Soc Clinical Investigation Inc, 2007)Targeting kinases is central to drug-based cancer therapy but remains challenging because the drugs often lack specificity, which may cause toxic side effects. Modulating side effects is difficult because kinases are ... -
An Efficient Water-Mediated Synthetic Route For The Alkylation of Heteroarenes
(Scientific Technical Research Council Turkey-Tubitak, 2018)An efficient synthetic route has been described for the alkylation of 1H-indole, 1H-benzimidazole, and 1H-benzotriazole. This approach features the alkylation of heteroaromatics through in situ generated enones from ketonic ... -
