gene therapy is in its development stage as a novel method for cancer treatment. liposomes look promising as gene delivery vectors; however, investigations have shown that these vesicles are not doing well in some cases. it was decided here to investigate the possibility of augmentation of liposomal gene delivery by chemical penetration enhancers.cationic liposome containing antisense oligonucl...

1,5-Diisopropyl-6-oxo-verdazyl free radicals were synthesized via the condensation of BOC protected isopropyl hydrazine with phosgene, deprotection with aqueous HCl, condensation with aldehydes to form tetrazanes and finally oxidation to give the free radicals. The introduction of isopropyl groups results in free radicals that show greater solubility in a variety of solvents and are more stable...

The actions of norepinephrine and isopropyl norepinephrine on the rhythnic plroperty of the heart were studied and compared with that of epinephrine. Norepinephrine does not abolish cardiac stan(1still byr carotid sinus stimulation, has no effect on the ventricular rate of heart block and induces a sinus bradyeardia. Isopropyl norepinephrine acts similarly to epinephrine in that it abolishes th...

The mass spectra of ethyl and isopropyl propionate and butyrate show rearrangement ions RlCOOH+ and RlC(OH)2+ formed by reactions [a] and [b]: R,COOR2+ --t RiCOOH+ + (R2 H), RlCOOR2+ --t R I C ( O H ) ~ + (R2 213). The mass spectra of ethyl-d2 propionate and butyrate show that both [a] and [b] occur with essentially complete scrambling of the alkoxy hydrogens. For the isopropyl esters the mass ...

volatile constituents of the seed kernel and leaf of cultivated moringa peregrina (forssk.) fiori, agricolt collected after hydrolysis were analyzed by gc and gc/ms. five glucosinolate degradation products which constituted almost the whole isolated oil of the seed kernel were identified to be: isobutyl isothiocyanate (94.0%), isopropyl isothiocyanate (4.9%), sec-butyl isothiocyanate (0.5%), n-...

Title of dissertation: USE OF TARTARIC ACID AND ISOPROPYL ALCOHOL IN THE REDUCTION OF HEXAVALENT CHROMIUM AND APPLICATION TO CHROMIUM CONTAMINATED SOILS AND CHROMITE ORE PROCESSING RESIDUE Dominic A. Brose, Doctor of Philosophy, 2012 Dissertation directed by: Professor Bruce R. James Department of Environmental Science and Technology Although chromium (Cr) is a naturally occurring metal, in the...

Friedel-Crafts reactions of isopropyl-substituted benzenes with phthalic anhydride in the presence of aluminium trichloride, followed by cyclization of the products with strong sulfuric acid give, as expected, anthraquinones. The syntheses, however, often afford more than one anthraquinone. In some cases the isopropyl groups migrate cleanly to other ring positions; in other cases they are lost.

Isopropyl (IPLA), N-methyl-N-isopropyl (MIPLA), N-ethyl-N-isopropyl (EIPLA), and N,N-diisopropyl (DIPLA) lysergamides were evaluated for lysergic acid diethylamide (LSD)-like activity. In rats trained to discriminate 0.08 mg/kg LSD tartrate from saline, each of the subject compounds completely substituted, with an ED50 two to three times larger than that of LSD except for DIPLA, which had an ED...
