Abstract: Generally, heterocyclic compounds are included in a large class of pharmacologically
active compounds. The indole scaffold in this category is widely distributed in nature and present
in many active compounds, especially anti-cancer agents. Due to its unique physicochemical and
biological properties, the indole platform has been considered a favorable scaffold in anti-cancer
drug design and development. Various indole compounds (synthetic, semisynthetic, and natural)
show remarkable anti-proliferative activity. According to the recent literature, this review describes
the role of indole scaffolds as anti-cancer agents. Indole was reported to induce anti-tumor activity
through multiple mechanisms, for example, Epidermal Growth Factor Receptors (EGFR), histone
deacetylase (HDAC), kinase, DNA-topoisomerases, and tubulin inhibition. The current review
focuses on some indole compounds with amazing effects against different types of cancers as there
are too many FDA-approved drugs, for example, osimertinib, alectinib, and anlotinib in NSCLC
treatment, panobinostat in multiple myeloma, midostaurin in acute myeloid leukemia treatment,
etc. Moreover, several compounds are still in clinical trials to treat different cancer types. Additionally,
there are some oxindole derivatives with potent inhibition against different types of tumors,
such as ovarian cancer, colorectal cancer, and prostate cancer. Different series of oxindoles
are promising and recommended for further studies due to their remarkable inhibition of tumor
cells. Accordingly, the collection of data on a pharmacologically significant motif might aid researchers
in further employing indoles in developing novel anti-cancer drugs with potentially fewer
side effects and higher potency against this rapidly spreading disease.
