专利号:US-4803287-A 优先权日:1986-04-16 标题 :Certain photochromic fulgide compounds and method for their synthesis 发明人:HIBINO JUNICHI; ANDO EIJI 权利人:AGENCY IND SCIENCE TECHN 摘要:The invention provides a photochromic material characterized by an improvnt in balance of the substituents in the conventional furylfulgides and represented by the general formula: ##STR1## (wherein R represents an alkyl chain having 5 to 31 carbon atoms). According to this molecular structure, a mutually appropriate steric hindrance is induced between the isopropylidence group and the long-chain alkyl group to make the regio isomer unstable, thus preventing the regio isomer from being by-produced while also inhibiting any isomerization reaction from occuring in the synthesis of the fulgide. Further, a good balance of hydrophilic part and hydrophobic part is produced to facilitate formation of a Langmuir-Blodgett film.
专利号:US-2025179033-A1 优先权日:2021-12-30 标 题 :New antiviral triazole derivatives, their synthesis and their use for treatment of mammalian viral infections 发明人:MAKAROV VADIM; RIABOVA OLGA; LANE THOMAS R; EKINS SEAN 权利人:COLLABORATIONS PHARMACEUTICALS INC; FEDERAL RES CENTER FUNDAMENTALS OF BIOTECHNOLOGY RUSSIAN ACADEMY OF SCIENCE 摘要:A family of triazole derivatives is described. Also described is the use of these triazole derivatives in treating or preventing viral infections, such as human immunodeficiency virus (HIV) infections, and the diseases caused by these infections, such as acquired immunodeficiency syndrome (AIDS). The triazole derivatives, for example, comprise a central triazole group with two substituents comprising an aryl or heteroaryl group. Exemplary derivatives showed excellent HIV inhibitory activity against both wild-type and selected mutant strains of HIV.
