Introduction:
Breast cancer is a widespread and life-threatening disease. While FDAapproved anti-BC drugs have improved survival rates, issues like drug resistance and adverse effects highlight the need for new therapeutic options. Molecular hybridization, a modern drug discovery strategy, combines different pharmacophores or frameworks into a single molecule to enhance pharmacological activity and improve treatment outcomes. Hybridizing two or more heterocyclic moieties has become a promising approach in anti-cancer drug discovery.
Methods:
This article reviews the role of heterocyclic hybrids in BC therapy, based on literature from 1995 to 2024 available in PubMed. Key heterocyclic hybrids, pyrimidine, triazole, indole, coumarin, beta-carboline, azepine, isoquinoline, benzoxepine, and platinum-core hybrids were included.
Results:
Triazole, in particular, was found to be a highly effective scaffold for BC treatment when combined with indole, pyridazinone, and steroid pharmacophores.
Discussion:
The article discusses novel molecular hybridization strategies, current BC treatment options, clinical studies, key functional groups, anti-apoptotic mechanisms, and protein-ligand interactions. Structure-activity relationships are explored to highlight desirable pharmacophoric features, aiding in the development of more effective BC therapies.
Conclusion:
Each heterocyclic hybrid class of BC comprises some salient features and potentials, which may be further investigated to obtain novel effective heterocyclic hybrid molecules in BC therapy.
Insights
Molecular hybridization using heterocyclic compounds shows promise for breast cancer (BC) therapy. Triazole-based hybrids, particularly when combined with indole, pyridazinone, or steroids, demonstrate significant potential for developing novel anti-cancer drugs.
Area of Science:
- Medicinal Chemistry
- Drug Discovery
- Oncology
Background:
- Breast cancer (BC) remains a significant global health challenge.
- Existing FDA-approved drugs face limitations like drug resistance and adverse effects, necessitating novel therapeutic strategies.
- Molecular hybridization offers a promising approach to enhance pharmacological activity and improve treatment outcomes for BC.
Purpose of the Study:
- To review the role of heterocyclic hybrids in breast cancer (BC) therapy.
- To explore novel molecular hybridization strategies for developing effective BC treatments.
- To identify key pharmacophoric features and mechanisms for improved anti-cancer drug design.
Main Methods:
- Comprehensive literature review of studies from 1995 to 2024 in PubMed.
- Inclusion of key heterocyclic hybrid classes such as pyrimidine, triazole, indole, coumarin, beta-carboline, azepine, isoquinoline, benzoxepine, and platinum-core hybrids.
- Analysis of structure-activity relationships, anti-apoptotic mechanisms, and protein-ligand interactions.
Main Results:
- Triazole-based heterocyclic hybrids emerged as particularly effective scaffolds for BC treatment.
- Optimal efficacy was observed when triazole was hybridized with indole, pyridazinone, and steroid pharmacophores.
- The review identified specific heterocyclic classes with salient features and therapeutic potential.
Conclusions:
- Heterocyclic hybrids represent a promising avenue for developing novel and more effective breast cancer (BC) therapies.
