Chemistry is traditionally divided into organic and inorganic chemistry. SDS of cas: 2971-79-1. The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 2971-79-1
The invention discloses a method for improving the water solubility of tryptanthrin, belonging to the technical field of cosmetics. The chromone is modified under the condition that the reactive group of the amine ketone is not changed; and the tryptamine is adopted as an intermediate to modify the tryptanthrone. The invention further discloses a method for synthesizing the mono-bromochromone derivative and N – benzylic ring – N N-alkanoic acid tryptanthrin derivative as well as a preparation method and application. N -benzyl ring – N N-alkanoic acid tryptanthrin derivative has excellent indoleamine -2, 3 – dioxygenase (IDO) inhibitor activity, and the like. The invention has wide application prospect, and can be used for treating diseases of cancer, ‘s disease, depression, cataract and the like with IDO-mediated pathologic characteristics of the tryptophan metabolic pathway. Under the condition that the active group of the amine ketone is not changed, the solubility. The method has the advantages, such as simple operation, mild conditions and the like, and is easy for industrial production. (by machine translation)
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.SDS of cas: 2971-79-1, you can also check out more blogs about2971-79-1
