Small molecule inhibitors offer targeted cancer therapy advantages but face challenges like resistance and low response rates. This review analyzes approved drugs and candidates to guide future development and overcome obstacles.
Area of Science:
- Oncology
- Pharmacology
- Drug Development
Background:
- Targeted therapy, particularly small molecule inhibitors, shows promise over traditional cancer treatments due to improved selectivity, efficacy, and tolerability.
- Small molecule inhibitors are crucial in oncology, with 88 FDA-approved agents, offering advantages like broad target engagement and central nervous system penetration.
- Despite progress, challenges persist, including low response rates, limited duration of response, toxicity, biomarker identification, and acquired resistance.
Purpose of the Study:
- To comprehensively review approved small molecule inhibitors and clinical candidates for cancer treatment.
- To organize agents by signaling pathways and inhibitor classification to provide a structured overview.
- To offer insights into overcoming resistance mechanisms and explore combination therapies for enhanced efficacy.
Main Methods:
- Systematic review of FDA-approved small molecule inhibitors for cancer.
- Analysis of pivotal drug candidates currently in clinical trials.
- Categorization of agents based on targeted signaling pathways and inhibitor class.
- Discussion of developmental challenges, resistance mechanisms, and combination strategies.
Main Results:
- Identified 88 FDA-approved small molecule inhibitors for cancer treatment.
- Detailed review of agents targeting various signaling pathways and classified by inhibitor type.
- Exploration of strategies to address common obstacles such as resistance and low response rates.
- Consideration of combination therapies involving small molecule inhibitors.
Conclusions:
- Small molecule inhibitors represent a significant advancement in cancer therapy, but development requires addressing key challenges.
- Strategies for overcoming resistance and optimizing combination therapies are crucial for improving patient outcomes.
- This review provides a valuable resource for researchers and developers in advancing small molecule inhibitor-based cancer treatments.

Inhibition of Cdk Activity
Targets for Drug Action: Overview
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
