专利号:US-11920040-B2 优先权日:2018-05-29 标 题 :Carborhodamine compounds and methods of preparation thereof 发明人:LUKHTANOV EUGENY A 权利人:ELITECHGROUP MDX LLC 摘要:The carborhodamine dyes disclosed herein are novel reagents suitable for automated incorporation of carborhodamine dyes into oligonucleotides that can be used in detection methods for nucleic acid targets. This disclosure provides an efficient and simple process for the preparation of carborhodamine compounds and introduces previously unknown reagents for the automated synthesis of oligonucleotide-carborhodamine conjugates.
专利号:US-4828849-A 优先权日:1988-01-14 标题 :Surfactant inhibition of dental plaque 发明人:LYNCH DONALD M; APPELBAUM BENJAMIN 权利人:WARNER LAMBERT CO 摘要:The invention provides an oral preparation or composition such as a mouthwash, mouthrinse, toothpaste and the like containing certain classes of surfactants which act to inhibit plaque formation by inhibiting the initial adherence of bacteria to the dentin surfaces and in the case of one class of surfactants additionally inhibiting the glucosyl transferase catalysis to prevent the synthesis of extracellular polysaccharides from sucrose. n The surfactants comprise substituted taurines, substituted isethionates and substituted hydroxy sultaines in which the substituents are long chain hydrocarbon radicals. The surfactants are employed in the aqueous-based oral compositions at concentrations between about 0.00001M to 0.1M to effect inhibition.
专利号:US-6150403-A 优先权日:1997-10-14 标 题 :Topical compositions for regulating the oily/shiny appearance of skin 发明人:BIEDERMANN KIMBERLY A; SCHUBERT HARRY L; PARRAN JR JOHN J 权利人:PROCTER & GAMBLE 摘要:The present invention relates to methods for inhibiting sebaceous gland activity in mammalian skin comprising administration of a topical composition comprising dehydroacetic acid or pharmaceutically acceptable salts thereof, and a dermatologically-acceptable carrier. The present invention also relates to methods and topical compositions further comprising agents which regulate the oily and/or shiny appearance of skin, and agents which treat acne and related skin disorders in mammalian skin and scalp. Methods of reducing sebum synthesis with the use of dehydroacetic acid, methods of regulating the oily and/or shiny appearance of skin, and methods of treating acne and other skin disorders are also encompassed by the present invention.
