Methyl-substitution of an iminohydantoin spiropiperidine β-secretase (BACE-1) inhibitor has a profound effect on its potency
摘要:
The IC50 of a beta-secretase (BACE-1) lead compound was improved similar to 200-fold from 11 mu M to 55 nM through the addition of a single methyl group. Computational chemistry, small molecule NMR, and protein crystallography capabilities were used to compare the solution conformation of the ligand under varying pH conditions to its conformation when bound in the active site. Chemical modification then explored available binding pockets adjacent to the ligand. A strategically placed methyl group not only maintained the required pKa of the piperidine nitrogen and filled a small hydrophobic pocket, but more importantly, stabilized the conformation best suited for optimized binding to the receptor.

The present invention is directed to spiropiperidine compounds of formula (I)
and tautomers thereof, which are inhibitors of the beta-secretase enzyme and that are useful in the treatment of diseases in which the beta-secretase enzyme is involved, such as Alzheimer's disease. The invention is also directed to pharmaceutical compositions comprising these compounds and the use of these compounds and compositions in the treatment of such diseases in which the beta-secretase enzyme is involved.
Conventional fungicidal compositions have had practical problems such that either a preventive effect or a curative effect is inadequate, the residual effect tends to be inadequate, or the controlling effect against plant diseases tends to be inadequate depending upon the application site, and a fungicidal composition to overcome such problems has been desired. The present invention provides a fungicidal composition containing a carboxylic acid amide derivative of the formula (I) or a salt thereof, as an active ingredient: wherein A is phenyl which may be substituted, benzodioxolanyl which may be substituted, or benzodioxanyl which may be substituted; B is 2- or 3-pyridyl which may be substituted; each of R
1
and R
2
is alkyl, or R
1
and R
2
may together form a 3- to 6-membered saturated carbon ring, provided that when B is 3-pyridyl which may be substituted, A is phenyl substituted by at least two substituents.
