Desaturation, dioxygenation, and monooxygenation reactions catalyzed by naphthalene dioxygenase from Pseudomonas sp. strain 9816-4
The stereospecific oxidation of indan and indene was examined with mutant and recombinant strains expressing naphthalene dioxygenase of Pseudomonas sp. strain 9816-4. Pseudomonas sp. strain 9816/11Expand
Oxidation of carbazole to 3-hydroxycarbazole by naphthalene 1,2-dioxygenase and biphenyl 2,3-dioxygenase.
Transformations were carried out by mutant strains which oxidize naphthalene and biphenyl to cis-dihydrodiols, and with a recombinant E. coli strain expressing the structural genes of naphthaene 1,2-dioxgenase from Pseudomonas sp. Expand
Syntheses and antimalarial activities of N-substituted 11-azaartemisinins.
In vitro and in vivo test data for a number of novel N-substituted 11-azaartemisinins, against drug-resistant strains of Plasmodium falciparum, show they possess antimalarial activities equal to or greater than that of artemisinin. Expand
Regiospecific and stereoselective hydroxylation of 1-indanone and 2-indanone by naphthalene dioxygenase and toluene dioxygenase
The biotransformation of 1-indanone and 2-indanone to hydroxyindanones was examined with bacterial strains expressing naphthalene dioxygenase (NDO) and toluene dioxygenase (TDO) as well as withExpand
Synthesis and antimalarial activities of several fluorinated artemisinin derivatives.
The carbonyl groups in several artemisinin derivatives were converted into geminal difluorinated compounds on treatment with diethylaminosulfur trifluoride. A number of other mono- andExpand
Pentafluorobenzyl chloroformate derivatization for enhancement of detection of amino acids or alcohols by electron capture negative ion chemical ionization mass spectrometry
Initial results indicate that the ECNICI-MS molar response of the decyl pentafluorobenzyl carbonate derivative is six-fold that of thedecyl pentahydrofluorobenzoate. Expand
Synthesis and reactions of 11-azaartemisinin and derivatives
Abstract 11-Azaartemisinin was prepared in 45% yield in a one pot, two-step sequence from the reaction of artemisinin with excess ammonia followed by acid treatment. Analogous reactions ofExpand
