Relevant academic research and scientific papers

Design and synthesis of a novel 2-oxindole scaffold as a highly potent and brain-penetrant phosphodiesterase 10A inhibitor

Highly potent and brain-penetrant phosphodiesterase 10A (PDE10A) inhibitors based on the 2-oxindole scaffold were designed and synthesized. (2-Oxo-1,3-oxazolidin-3-yl)phenyl derivative 1 showed the high P-glycoprotein (P-gp) efflux (efflux ratio (ER) = 6.

Design, synthesis, and SAR of new pyrrole-oxindole progesterone receptor modulators leading to 5-(7-fluoro-3,3-dimethyl-2-oxo-2,3-dihydro-1H-indol-5-yl)- 1-methyl-1H-pyrrole-2-carbonitrile (WAY-255348)

We have continued to explore the 3,3-dialkyl-5-aryloxindole series of progesterone receptor (PR) modulators looking for new agents to be used in female healthcare: contraception, fibroids, endometriosis, and certain breast cancers. Previously we reported

Process for preparing 3,3-disubstituted oxindoles and thio-oxindoles

Methods for preparing oxindole and thio-oxindole compounds are provided, which compounds are useful as precursors to useful pharmaceutical compounds. Specifically provided are methods for preparing 5-pyrrole-3,3-oxindole compounds and 5-(7-fluoro-3,3-dimethyl-2-oxo-2,3-dihydro-1H-indol-5-yl)-1-methyl-1H-pyrrole-2-carbonitrile. Also provided are methods for preparing iminobenzo[b]thiophene and benzo[b]thiophenone compounds.

Progesterone receptor antagonists, contraceptive regimens, and kits

A method of contraception is provided which involves delivery of 21 to 27 consecutive days of one or more PR antagonists in the absence of a progestin, estrogen, or other steroidal compound, followed by 1 to 7 days without any active agent. Also described is a pharmaceutically useful kit to facilitate delivery of this regimen.
