摘要:在甲醇中辐照芳氧基乙酮时,会产生2-甲基苯并呋喃以及通过aro-Ch2键断裂形成的苯酚.间位取代的芳氧基乙酮还会通过光反应反应生成二甲氧基乙缩醛.氯代,溴代和硝基取代基会延缓或阻止光反应的进行.当使用对甲氧基苯氧基乙酮进行辐照时,反应生成苯并呋喃的中间体被分离出来,并被证实是邻位重排的产物.

标 题 :Enzymatic synthesis of chiral amines using -2-amino propane as amine donor

摘要:2-Aminopropane is used as the amine donor in the stereoselective synthesis of a chiral amine from a ketone with a transaminase. In a typical embodiment, (S)-1-methoxy-2-aminopropane is prepared by bringing methoxyacetone into contact with a transaminase in the presence of 2-aminopropane as an amine donor until a substantial amount of methoxyacetone is converted to (S)-1-methoxy-2-aminopropane and 2-aminopropane is converted to acetone. In a second embodiment, L-alanine is prepared by bringing pyruvic acid into contact with a transaminase in the presence of 2-aminopropane as an amine donor.

摘要:A process for producing an azulene derivative useful as a Na + -glucose cotransporter inhibitor, which is high in yield, is simple in operation, is low in cost, is suited for environmental protection, and is advantageous industrially, the process being characterized by reducing and deprotecting at least one compound selected from penta-acyl compounds and tetra-acyl compounds or salts thereof to obtain a C-glycoside compound; and a useful intermediate for synthesis of such an azulene derivative, obtained in the course of the above process.

摘要:This invention provides improved biological synthesis of the apocarotenoid α-ionone in Saccharomyces cerevisiae. The final native step involved in the natural apocarotenoid pathway depends on an endogenous farnesyl pyrophosphate synthase (FPPs). From there, heterologous geranylgeranyl pyrophosphate synthase (crtE), phytoene synthase (crtB), phytoene desaturase (crtI), lycopene ε-cyclase (LycE) and a Carotenoid Cleavage Dioxygenase (CCD1) are required to complete the synthesis of α-ionone. Lycopene ε-cyclase from lettuce (Lactuca sativa) or modified cyclase from Arabidopsis thaliana was used to overproduce lycopene which was then cleaved by the carotenoid cleavage dioxygenase from Petunia hybrida (Ph-CCD1).

摘要:An ion exchange resin catalyst containing sulfonated styrene-divinylbenzene copolymer, a porous structure with micropore area and transfer pass networks, the transfer pass network is composed of main pass networks and branch pass networks, in non-swollen state, the pore size of the main pass network is 9x103-38x103 nanometer and the pore size of the branch pass network is 20-150 manometer, the pore size of the micropore area pass is 5-20 nanometer, wherein the pore capacity of the micropore pass with the pore size of 5-10.4 nm is more than 50% of the total pore capacity of the micropore area, and the ratio of the pore capacity of the micropore area to that of the transfer network area is 0.25-1.1. The catalyst is useful to condense phenols with ketones.

标题:Process for preparing conjugates of methyltrithio antitumor agents

摘要:This invention describes carrier-drug conjugates prepared from disulfide analogs of the calicheamicin family of potent antitumor antibiotics and their derivatives, as well as similar analogs from related antitumor antibiotics such as the esperamicins. The carrier can be an antibody, growth factor, or steroid which targets an undesired population of cells, such as those of a tumor. Whole protein carriers as well as their antigen-recognizing fragments and their chemically or genetically manipulated counterparts are useful for the targeting portion of the conjugates. This invention includes compounds required for the synthesis of these conjugates, appropriate pharmaceutical compositions of the carrier-drug conjugates, and their method of use.
