Synthesis and diverse biological activities of substituted indole β-carbolines: a review

Abstractβ-Carboline bearing indole is one of the heterocyclic compounds that play a vital role in medicinal chemistry with various pharmacological effects such as anticancer, anti-acetylcholinesterase, anti-inflammation, antimalarial, antibacterial, anti-diabetic, and antioxidant. Over the last two decades, many studies on the synthesis and biological activity of indole β-carboline compounds have been conducted yet there is no appropriate data summary has been presented. Thus, the goal of this review was to highlight the synthesis pathway and bioactivity of substituted indole β-carboline reported from 2005 to date. In addition, this will encourage further investigation into the synthesis and evaluation of new indole β-carboline, in the hope of contributing to the development of potentially new medications for the treatment of various ailments.Keywords: Biological activityβ-carbolineindole β-carbolinesynthesis Disclosure statementNo potential conflict of interest was reported by the authors.Additional informationFundingThis work was financially supported under the Fundamental Research Grant Scheme (FRGS/1/2022/STG04/UITM/02/7) funded by the Ministry of Education, Malaysia.
