3-Epioleanolic acid and oleanonic acid possess varying degrees of agonist activity on uterine smooth muscle with minor changes in the molecular structure affecting its intrinsic activity on uterine muscle.

4-Hydroxycoumarin, a coumarin derivative.4-Hydroxycoumarin serves as an immediate precursor of 4-hydroxycoumarin (4HC) type anticoagulants (for example, warfarin).?4-Hydroxycoumarin derivatives ?are employed as the anticoagulant, antibacterial, antifungal, antiviral, antitumor, antiprotozoal, insecticidal, antimycobacterial, antimutagenic, antioxidant, anti-inflammatory agents, HIV protease inhibitors and tyrosine kinase inhibitors.

TTNPB, a potent RAR agonist, inhibits binding of [3H]tRA of human RARα (IC50: 5.1 nM), β (IC50: 4.5 nM), and γ (IC50: 9.3 nM), respectively.
