The synthesis of a series of substituted pyrazolo corticoids is described. Of these 11beta,17alpha,21-trihydroxy-6,16alpha-dimethyl-4,6-pregnadieno[3,2-c]-2'-(4-pyridly)pyrazole (21) shows an excellent separation of systemic to local activity in the model animal test. Compound 21 exhibits high vasoconstriction activity in human volunteers and is clinically effective in the treatment of psoriasis.
The new herbicide, 2-cyclohexyl-4-iodo-1,5-dimethyl-1,2-dihydro-3H-pyrazol-3-one, is described and its preparation and use to control undesired plant growth are exemplified.

The design and construction of a series of novel aminothiazole-derived gamma-secretase modulators is described. The incorporation of heterocyclic replacements of the terminal phenyl D-ring of lead compound 1 was conducted in order to align potency with favorable drug-like properties. gamma-Secretase modulator 28 displayed good activity for in vitro inhibition of Abeta42, as well as substantial improvement
