Abstract:
ABSTRACTPolymorphism in thePlasmodium falciparumchloroquine resistance transporter (PfCRT) was shown to cause chloroquine resistance. In this report, we examined the antimalarial potential of novel 3-halo chloroquine derivatives (3-chloro, 3-bromo, and 3-iodo) against chloroquine-susceptible and -resistantP. falciparum. All three derivatives inhibited the proliferation ofP. falciparum; with 3-iodo chloroquine being most effective. Moreover, 3-iodo chloroquine was highly effective at potentiating and reversing chloroquine toxicity of drug-susceptible and -resistantP. falciparum.

Abstract:
Novel 13α-estrone derivatives were synthesized by Sonogashira coupling. Transformations of 2- or 4-iodo regioisomers of 13α-estrone and its 3-methyl ether were carried out under different conditions in a microwave reactor. The 2-iodo isomers were reacted with para-substituted phenylacetylenes using Pd(PPh3)4 as catalyst and CuI as a cocatalyst. Coupling reactions of 4-iodo derivatives could be achieved by changing the catalyst to Pd(PPh3)2Cl2. The product phenethynyl derivatives were partially or fully saturated. Compounds bearing a phenolic OH group furnished benzofurans under the conditions

The fluoro-derivative 3b was obtained from2b in the reaction with tetrabutyl ammonium fluoride. The deprotection of the 3-hydroxyl group was achieved by action of hydrogen in presence of Pd/C as a catalyst, yielding six new 3-hydroxy-16,17-seco-estrone derivatives.

Abstract:
Through careful choice of reaction conditions, alkylation of estradiol with chloromethyl methyl ether may yield either the 3,17β-bis(methoxymethy1) ether or the 3-methoxymethyl ether derivative. Treatment of either of these protected estradiols with s- butyllithium, then with trimethylsilyl chloride affords, regioselectively, the 2-trimethylsilyl derivatives which can conveniently be converted into 2-bromo-or 2-iodo-estradiol.

Abstract:
The use of radiolabeled non-natural amino acids can provide high contrast SPECT/PET metabolic imaging of solid tumors. Among them, radiohalogenated tyrosine analogs (i.e., [123I]IMT, [18F]FET, [18F]FDOPA, [123I]8-iodo-L-TIC(OH), etc.) are of particular interest. While radioiodinated derivatives, such as [123I]IMT, are easily available via electrophilic aromatic substitutions, the production of radiofluorinated aryl tyrosine analogs was a long-standing challenge for radiochemists before the development of innovative radiofluorination processes using arylboronate, arylstannane or iodoniums salts

The reaction of 6-iodo-, 9-benzyl-6-chloropurine and 7-benzyl-6-chloropurine with butyl acrylate, acrylonitrile, methyl vinyl ketone or methyl methacrylate under conditions of the Heck reaction in the presence of TlOAc or AgOAc afforded N1-alkylhypoxanthine derivatives. Formation of these unexpected products can be rationalised as a Tl+- or Ag+-assisted substitution of halogen with acetate anion. The 6-acetoxypurine derivative thus formed then eliminates ketene and gives 7-benzyl- or 9-benzylhypoxanthine. Conjugate addition of these compounds onto Michael acceptors furnishes the N1-substituted

The most common routes to pyrazino[1,2-a]indoles involve cyclization of indole derivatives containing a formyl, keto, ester, or nitrile function at the 2-position. Indolo[1,2-a]quinoxalines are most readily accessed via cyclization of 1-(aryl)-1H-indoles, where the aryl group is substituted at the 2-position by either amino, iodo, or nitro functionality.

In the last fifteen years, a wide number of various chiral auxiliaries have been employed in DKR processes occurring in different types of reactions, such as substitution reactions involving configurationally-labile alkyl halides or configurationally-labile anions, esterification and transesterification reactions, cyclocondensation reactions, reductions, cycloaddition reactions, and miscellaneous reactions.

Abstract:
The use of spreadsheet programs (Lotus [1], Excel [2], etc.) as an optical design and production fabrication tool is reviewed. The common problem of melt and thickness recalculation prior to assembly is demonstrated using two approaches: (1) the spreadsheet preprocesses and writes a file for batch processing by a commercial optical design program, and (2) the spreadsheet uses matrix algebra and a partial derivative matrix to compute the respacing without any additional ray tracing.
