Cancer is known as one of the serious causes of mortality among the world population.

In the constant search for new anticancer agent alternatives, β-carboline alkaloids have been identified as good candidates for a new chemotherapy drug. β-carboline compounds M25, M56 and M62 were synthesised, and their purities were confirmed using gas chromatography-mass spectrometry (GC-MS) analysis
