  • Patent number: 7417156
    Abstract: In only two steps and in 65% overall yield, natural trioxane artemisinin (I) was converted on gram scale into C-10-carba trioxane dimer (3). This new, very stable dimer was then transformed easily in one additional step into four different dimers (4-7). Alcohol and diol dimers (4 and 5) and ketone dimer (7) are 10 times more antimalarially potent in vitro than artemisinin (I), and alcohol and diol dimers (4 and 5) are strongly inhibitory but not cytotoxic toward several human cancer cell lines. Water-soluble carboxylic acid derivatives (8a-10c and 12) were easily prepared from dimers (4-6); they are thermally stable even at 60° C. for 24 hours, are more orally efficacious as antimalarials than either artelinic acid or sodium artesunate, and have potent and selective anticancer activities.

    Abstract: Inventors have developed a chromophore (nitrodibenzylfuranyl, or NBDF) for ultra efficient uncaging of a caged substrate (e.g., an organic molecule such as, for example, an amino acid, a biological molecules, such as, for example, second messengers inside cells). Photolysis of a NBDF derivative of EGTA (i.e. caged calcium) is about 50 times more efficient than others calcium cages (the quantum yield of photolysis is 0.6 and the extinction coefficient is 18,400. NDBF-EGTA has a 2-photon cross section of about 0.3-0.6 GM).

A fluorescent molecule may be attached to polymer along with the trisubstituted amine or trisubstituted phosphine. Also, the benzyl halide may be reacted with a ?-electron donor, such as a vinyl naphthalene or vinylanthracene to form a co-polymer which is polymerizable with the trisubstituted amine and/or trisubstituted phosphine. By controlling the reaction parameters it is possible to obtain either a water-soluble or partial water soluble or insoluble compound crosslink polymer.

  • Patent number: 6346615
    Abstract: Spiroadamantyl dioxetanes bearing an alkoxy substituent, and an aromatic substituent of phenyl or naphthyl on the dioxetane ring can be activated to chemiluminesce if the aromatic substituent bears a moiety designated OX, wherein the X is cleaved by an enzyme with which the dioxetane is permitted to come in contact with. The T½ kinetics of the chemiluminescent reaction, as well as the signal intensity, or quantum yield of the chemiluminescent reaction, can be altered by selection of an electron-withdrawing or an electron-donating group Z, at positions on the aromatic substituent other than those adjacent the point of attachment to the dioxetane. Signal strength can further be enhanced by recognized chemiluminescent enhancers.

  • Patent number: 6313317
    Abstract: Disclosed is a ruthenium-phosphine complex usable as the catalyst giving a high enantiomer excess in an asymmetric reaction and a method for producing the complex. The ruthenium-phosphine complex is represented by formula (1): [{(RuX(L)}2(&mgr;-X)3]−[R22NH2]+  (1) wherein R2 represents hydrogen, alkyl, cycloalkyl or benzyl and L represents a diphosphine ligand represented by formula (2): wherein R1 represents an optionally substituted phenyl group and X represents a halogen atom. The method for preparing a ruthenium-phosphine complex represented by formula (1) is characterized in that a ruthenium complex represented by the formula [RuX(arene)(L)]X and an ammonium salt represented by the formula R22NH.HX are reacted with each other.
