    Area of Science:

    • Pharmacology
    • Medicinal Chemistry

    Background:

    • Prostaglandin F2alpha (PGF2alpha) plays a role in various physiological processes.
    • Developing selective antagonists for PGF2alpha receptors is a key area in drug discovery.

    Purpose of the Study:

    • To present a rationale for developing prostaglandin F2alpha receptor antagonists.
    • To synthesize and evaluate novel 2-indanpropionic acid derivatives as potential PGF2alpha antagonists.

    Main Methods:

    • Synthesis of 2-indanpropionic acid analogues, including 5,6-(dibenzyloxy)-1-oxo-2-propyl-2-indanpropionic acid (3).
    • In vitro pharmacological evaluation using mouse ileum assays to assess antagonism of PGF2alpha, acetylcholine, and KCl.

    Main Results:

    • Compound 3 exhibited selective antagonism of PGF2alpha compared to acetylcholine and KCl.

  • Other non-benzylated 2-indanpropionic acid analogues showed significantly lower activity and lacked selectivity.

    • Conclusions:

    • The synthesized compound 5,6-(dibenzyloxy)-1-oxo-2-propyl-2-indanpropionic acid (3) is a promising selective PGF2alpha receptor antagonist.
    • This compound serves as a lead structure for further optimization in the development of PGF2alpha-targeted therapeutics.
