The invention relates to pharmaceutical and cosmetic compositions comprising at least one benzisothiazolinone-1-dioxide derivative with the formula:
where R¹ can be hydrogen, and R² can be certain generally hydrophobic C₈-C₂₀ aliphatic groups or the group:
where R⁵ is aliphatic or else R² is a saturated or unsaturated C₂-C₆ group ending in an aromatic nucleus.
These compositions can be used to inhibit elastases such as human leucocytic elastase. They may be applied topically as a cosmetic.
Many of the benzisothiazolinone-1-dioxide derivative specified as active ingredient in such compositions are novel compounds.
Disclosed are compounds of formulae:
and salts, hydrates, or solvates thereof, where R1, R2, R3, R5, and R6 are defined herein, compositions containing these compounds, methods of preparing these compounds, and methods of using these compounds in a variety of applications, such as a surfactant or additive in personal care products.
