synthesized smoothly via cycloaddition reaction catalyzed by potassiumtert-butoxide. Results: A small library of target compounds was prepared under optimized reaction conditions in moderate to good yields. The reaction mechanism has been proposed. Conclusion: Potassiumtert-butoxide is an environmentally friendly and efficient catalyst for the cycloaddition reaction of α -mercapto ketones and 3-(subs

This application relates to thiophene azo dyes for use as hueing agents, laundry care compositions comprising such thiophene azo dyes, processes for making such thiophene azo dyes, and laundry care compositions and methods of using the same. The thiophene azo dyes contain a formally charged moiety and are generally comprised of at least two components: at least one chromophore component and at least one polymeric component. Suitable chromophore components generally fluoresce blue, red, violet, or purple color when exposed to ultraviolet light, or they may absorb light to reflect these same shades. These thiophene azo dyes are advantageous in providing a hueing effect, for example, a whitening effect to fabrics, while not building up over time and causing undesirable blue discoloration to the treated fabrics. The thiophene azo dyes are also generally stable to bleaching agents used in laundry care compositions.

The identification of a novel series of small molecule BET inhibitors is described. Using crystallographic binding modes of an amino-isoxazole fragment and known BET inhibitors, a structure-based drug design effort lead to a novel isoxazole azepine scaffold. This scaffold showed good potency in biochemical and cellular assays and oral activity in an in vivo model of BET inhibition.
