- Development of a pilot-plant-scale synthesis of an alkylated dihydrobenzothiadiazole S, S-dioxide: Incorporation of a late-stage mitsunobu reaction
-
The process used to prepare a functionalized dihydrobenzothiadiazole S,S-dioxide on a pilot plant scale is described. Key changes to the original synthesis included: modifying SNAr reaction conditions between a substituted aniline and 2-fluoron

- Discovery of novel selective norepinephrine reuptake inhibitors: 4-[3-Aryl-2,2-dioxido-2,1,3-benzothiadiazol-1(3 H)-yl]-1-(methylamino)butan-2- ols (WYE-103231)
-
Structural modification of a virtual screening hit led to the identification of a new series of 4-[3-aryl-2,2-dioxido-2,1,3-benzothiadiazol- 1(3H)-yl]-1-(methylamino)butan-2-ols which are potent and selective inhibitors of the norepinephrine transporter over both the serotonin and dopamine transporters. One representative compound S-17b (WYE-103231) had low nanomolar hNET potency (IC50 = 1.2 nM) and excellent selectivity for hNET over hSERT (>1600-fold) and hDAT (>600-fold). S-17b additionally had a good pharmacokinetic profile and demonstrated oral efficacy in rat models of ovariectomized-induced thermoregulatory dysfunction and morphine dependent flush as well as the hot plate and spinal nerve ligation (SNL) models of acute and neuropathic pain.
