Current status on development of steroids as anticancer agents

Area of Science:

• Medicinal Chemistry
• Pharmacology
• Organic Chemistry

Background:

• Steroids are crucial biodynamic molecules with significant roles in human physiology.
• Their interaction with nuclear receptors makes them valuable for drug development, especially for receptor-mediated diseases.
• Steroid biochemistry and modifications are areas of intense research interest.

Purpose of the Study:

• To review recent advancements in steroidal lead molecules for drug development.
• To highlight successful anticancer agents derived from steroidal pharmacophores.
• To provide an update on steroid-based enzyme inhibitors, antiestrogens, and cytotoxic agents.

Main Methods:

• Review of scientific literature over the past 25 years.
• Focus on rational modifications of the steroid nucleus (perhydrocyclopentanophenanthrene).
• Identification and categorization of various steroidal derivatives (natural and synthetic).

Main Results:

• Several successful steroidal anticancer lead molecules have emerged, including exemestane, SR16157, fulvestrant, and 2-methoxyestradiol.
• Diverse steroidal compounds, including enzyme inhibitors, antiestrogens, and cytotoxic agents, have been developed.
• Modifications of the steroid scaffold have yielded potent therapeutic candidates.

Conclusions:

• Steroidal pharmacophores continue to be a rich source for developing novel therapeutic agents, particularly in oncology.
• Rational drug design based on steroid modifications offers a promising strategy for treating various diseases.
• The review underscores the ongoing importance of steroid derivatives in medicinal chemistry and drug discovery.
