Process Development and Scale-Up for the Preparation of the 1‑Methyl-quinazoline-2,4-dione Wnt Inhibitor SEN461
A practical
and scalable route to the Wnt inhibitor SEN461 <b>1</b> is described
herein. The optimized route consists of nine
chemical steps. The intermediates are solids and were isolated by
filtrations. Critical reactions steps in the medicinal chemistry route
were modified for an initial scale-up process, and as a result, we
developed a synthetic procedure for the preparation of multihundred
gram quantities of the final product. A further process development
for the phase 1 clinical batch campaign is reported
<i>N</i>‑[5-(5-Fluoropyridin-3-yl)‑1<i>H</i>‑pyrazol-3-yl]-4-piperidin-1-ylbutyramide (SEN78702, WYE-308775): A Medicinal Chemistry Effort toward an α7 Nicotinic Acetylcholine Receptor Agonist Preclinical Candidate
α7 nicotinic acetylcholine receptors (α7
nAChR) represent
promising therapeutic candidates for the treatment of cognitive impairment
associated with Alzheimer’s disease (AD) and schizophrenia.
A medicinal chemistry effort around previously reported compound <b>1</b> (SEN15924, WAY-361789) led to the identification of <b>12</b> (SEN78702, WYE-308775) a potent and selective full agonist
of the α7 nAChR that demonstrated improved plasma stability,
brain levels, and efficacy in behavioral cognition models
