Multi-Target Directed Indole Based Hybrid Molecules in Cancer Therapy : An Up-To-Date Evidence-Based Review

Area of Science:

• Oncology
• Medicinal Chemistry
• Drug Discovery

Background:

• Cancer remains a complex, multifactorial disease with many incurable types despite extensive research.
• The traditional "one-compound-one-target" drug discovery model has proven insufficient, leading to the adoption of multi-target strategies.
• Hybrid compounds, linking multiple pharmacophores, are emerging as a key strategy to address complex diseases like cancer.

Purpose of the Study:

• To review novel hybrid compounds incorporating an indole moiety for enhanced anti-cancer activity.
• To explore the synergistic effects and multi-target capabilities of these advanced drug candidates.
• To discuss the challenges and limitations in the development of indole-based hybrid anti-cancer agents.

Main Methods:

• Literature review of hybrid compounds featuring an indole nucleus.
• Analysis of studies demonstrating dual or multiple intracellular actions.
• Evaluation of synergistic effects and mechanisms of action against cancer.

Main Results:

• Hybrid compounds demonstrate improved pharmacological potency and reduced drug resistance compared to single agents.
• Indole-based hybrid molecules show significant therapeutic potential through simultaneous or sequential action on multiple targets.
• Synergistic effects arise from the combined action of independently acting pharmacophores within a single molecule.

Conclusions:

• Hybrid compounds represent a significant advancement in cancer therapy, moving beyond single-target approaches.
• Indole-containing hybrid molecules offer a versatile platform for developing potent and effective anti-cancer drugs.
• Further research into overcoming current limitations is crucial for the clinical translation of these promising agents.
