The invention provides compositions and methods for delaying the onset of delivery in a pregnant subject, such as a pregnant human subject, that is undergoing or at risk of undergoing preterm labor at a gestational age of from about 24 weeks to about 34 weeks. Using the compositions and methods described herein, such subjects may be administered nifedipine in combination with a prostaglandin F2α (PGF2α) antagonist. Exemplary PGF2α receptor antagonists that may be used for the treatment or prevention of preterm labor as described herein include 1,3-thiazolidine-2-carboxamide compounds, such as (3S)-3-({[(2S)-3-(biphenyl-4-ylsulfonyl)-1,3-thiazolidin-2-yl]carbonyl}-amino)-3-(4-fluorophenyl)propyl L-valinate or a pharmaceutically acceptable salt thereof (e.g., (3S)-3-({[(2S)-3-(biphenyl-4-ylsulfonyl)-1,3-thiazolidin-2-yl]carbonyl}-amino)-3-(4-fluorophenyl)propyl L-valinate hydrochloride. Using the compositions and methods described herein, a subject may be dosed with a PGF2α receptor antagonist and a reduced amount or frequency of nifedipine relative to the amount or frequency of nifedipine that would otherwise be used if the nifedipine were given in the absence of the PGF2α receptor antagonist.

The present application relates to a hydrogen peroxide-responsive Keap1-Nrf2 PPI inhibitor prodrug, and a preparation method therefor. The hydrogen peroxide-responsive Keap1-Nrf2 PPI inhibitor prodrug pro2 has a chemical structure as shown below. By modifying a key carboxyl pharmacophore in a Keap1-Nrf2 inhibitor with a H.sub.2O.sub.2-responsive thiazolidinone moiety, a novel ROS-responsive antioxidant prodrug pro2 is synthesized. The H.sub.2O.sub.2 activated prodrug pro2 can simultaneously achieve targeted activation of Nrf2 and enhancement of therapeutic efficacy in the body. The prodrug is based on the concept of ROS activation-ROS clearance therapy, is the first example of a H.sub.2O.sub.2-responsive prodrug suitable for oral administration, and is expected to be used clinically by virtue of the characteristics of druggability and high targeting ability.
