TTK is an essential spindle assembly checkpoint enzyme in many organisms. It plays a central role in tumor cell proliferation and is aberrantly overexpressed in a wide range of tumor types. We recently reported on a series of potent and selective TTK inhibitors with strong antiproliferative activity in triple negative breast cancer (TNBC) cell lines (8: TTK IC50 = 3.0 nM; CAL-51 IC50 = 84.0 nM). Inspired by previously described potent tricyclic TTK inhibitor 6 (TTK IC50 = 0.9 nM), we embarked on a structure-enabled design and optimization campaign to identify an improved series with excellent potency, TTK selectivity, solubility, CYP inhibition profile, and in vivo efficacy in a TNBC xenograft model. These efforts culminated in the discovery of 25 (TTK IC50 = 3.0 nM; CAL-51 IC50 = 16.0 nM), which showed significant single-agent efficacy when dosed iv in a TNBC xenograft model without body weight loss.

GABA agonists. Synthesis and structure-activity studies on analogues of isoguvacine and THIP

A series of analogues of the specific GABA receptor agonists isoguvacine, isonipecotic acid, and THIP (4,5,6,7-tetrahydroisoxazolo[5,4-c]pyridin-3-ol) have been synthesized and tested as inhibitors of the binding of 3H-GABA to GABA receptor sites on rat brain membranes in vitro. Introduction of a hydroxy group into the 3- or 4-position of isonipecotic acid results in compounds with considerably reduced receptor affinity. The 7-membered ring analogues of isoguvacine and isonipecotic acid are more than two orders of magnitude weaker than the parent compounds. Replacement of the 3-isoxazolol unit of THIP by related heterocyclic rings also result in dramatic loss of activity. Thus iso-THIP (4,5,6,7-tetrahydroisoxazolo[3,4-c]pyridin-3-ol) is a weak inhibitor of 3H-GABA binding, whereas the 3-pyrazolol THIP analogues are inactive.
