Protein kinases as therapeutic targets to develop anticancer drugs with natural alkaloids

Area of Science:

• Biochemistry
• Pharmacology
• Oncology

Background:

• Protein kinases are crucial regulators of cellular processes and are significant targets for anticancer drug development.
• Existing protein kinase inhibitors face challenges with drug resistance and off-targeting, limiting their clinical efficacy.
• Alkaloids, a class of natural products, exhibit diverse biological activities, including potent anticancer effects via protein kinase inhibition.

Purpose of the Study:

• To review key protein kinases targeted by alkaloids in cancer, including MAPK, PI3K/AKT/mTOR, and JAK/STAT pathways.
• To highlight specific binding sites of alkaloids on protein kinases and their role in overcoming drug resistance.
• To discuss the challenges and future prospects of developing alkaloids as novel anticancer agents.

Main Methods:

• Literature review of studies on alkaloids and their anticancer mechanisms.
• Identification of key protein kinase signaling pathways targeted by alkaloids.
• Analysis of alkaloid interactions with protein kinases and their impact on drug resistance.

Main Results:

• Alkaloids effectively inhibit critical protein kinases, including MAPK, PI3K/AKT/mTOR, and JAK/STAT signaling pathways.
• Specific targeting sites on protein kinases by alkaloids are identified, offering potential for overcoming resistance.
• Alkaloids demonstrate significant tumor growth suppression through modulation of cancer cell signaling.

Conclusions:

• Alkaloids represent a promising class of natural compounds for cancer treatment by targeting diverse protein kinase pathways.
• Further research into alkaloid mechanisms and drug resistance reversal could lead to novel, clinically valuable anticancer agents.
• The development of novel alkaloid-based anticancer therapies holds significant promise for future clinical applications.
