专利号:WO-2025136243-A1 优先权日:2023-12-20 标题:Mechanochemical synthesis of histamine h1-receptor antagonists 发明人:AYDONAT SIMAY; OZEL MERTCAN; YIGITBASI JOANNA MARIANNA; BAYTEKIN BILGE; COLACINO EVELINA 权利人:IHSAN DOGRAMACI BILKENT UNIV; CENTRE NAT RECH SCIENT 摘要:The present invention relates to mechanochemical synthesis of histamine antagonists which are benzhydryl ethers and unsymmetrically disubstitutes piperazines and salts thereof. Said antihistamine active pharmaceutical ingredients can be diphenhydramine hydrochloride, cyclizine hydrochloride and diphenylpyraline hydrochloride. These antihistamines are used in the treatment of allergies, hives, hay fever (allergic rhinitis), conjunctivitis, reactions to insect bites and sings, nausea, motion sickness, insomnia.
专利号:US-6417380-B1 优先权日:1987-12-31 标 题 :Synthesis of 1,2-dioxetanes and intermediates therefor 发明人:BRONSTEIN IRENA Y; EDWARDS BROOKS 摘要:Compounds having the formula: n wherein T is a polycycloalkylidene group (e.g., adamant-2-ylidene); R is a C 1-20 alkyl, aralkyl or cycloalkyl group; and Y is a fluorescent chromophore (e.g., n m-phenylene), produced by reacting a compound having the formula: n with an R-ylating agent (e.g., R 2 SO 4 ) in the presence of an alkali metal alkoxide in a polar aprotic solvent. Also, compounds having the formula: n are produced by reacting a compound having the formula: n with n wherein X is an electronegative leaving group (e.g., a halogen anion such as chloride ion) in the presence of a Lewis base (e.g., a trialkyl-amine) dissolved in an aprotic organic solvent (e.g., benzene or toluene). Also, compounds having the formula n are produced by reacting a compound of the formula n with a tetra-O-acylated-O-hexopyranoside halide, then hydrolyzing off the protective acyl groups. The aforementioned compounds and procedures are useful in the synthesis of enzyme-cleavable 1,2-dioxetane ring systems that can serve as members of a binding pair employed, for example, in chemiluminescent immunoassays, DNA probe assays, and direct assays for an enzyme.

Also, compounds having the formula: ##STR3## are produced by reacting a compound having the formula: ##STR4## wherein X is an electronegative leaving group (e.g., a halogen anion such as chloride ion) in the presence of a Lewis base (e.g., a trialkyl-amine) dissolved in an aprotic organic solvent (e.g., benzene or toluene). Also, compounds having the formula ##STR5## are produced by reacting a compound of the formula ##STR6## with a tetra-O-acylated-O-hexopyranoside halide, then hydrolyzing off the protective acyl groups. The aforementioned compounds and procedures are useful in the synthesis of enzyme-cleavable 1,2-dioxetane ring systems that can serve as members of a binding pair employed, for example, in chemiluminescent immunoassays, DNA probe assays, and direct assays for an enzyme.
