The present disclosure is directed to a cleavable agent for enhanced magnetic resonance generally corresponding to the formula Y-L-R, wherein Y represents a catalyst-binding moiety having at least one isotopically labeled heteroatom, L represents a cleavable bond, and R represents a hyperpolarized payload having at least one isotopically labeled carbon. Also disclosed herein is a method of cleaving the cleavable agent for enhanced magnetic resonance.

The present disclosure provides certain tetrahydro-1H-cyclopenta[cd]indene compounds that are Hypoxia Inducible Factor 2α (HIF-2α) inhibitors and are therefore useful for the treatment of diseases treatable by inhibition of HIF-2α. Also provided are pharmaceutical compositions containing such compounds and processes for preparing such compounds.

The present invention relates to esters of carboxylic acid agrochemicals comprising a labile protecting group and having formula (I). Certain of the esters of carboxylic acid agrochemicals do not undergo hydrolysis to a significant degree in the dark, but are cleaved to regenerate the parent carboxylic acid agrochemical when exposed to light. Others of the esters of carboxylic acid agrochemicals undergo hydrolysis under both light and dark conditions. The present invention further relates to methods for the controlled release of a carboxylic acid agrochemicals, and to methods of controlling unwanted plants comprising applying to the unwanted plants an ester of a carboxylic acid agrochemical.
