Short-lived radioisotopes separated from radionuclide generators are widely used. Possibilities of labeling with the daughter nuclides of the com. available Mo/Tc-, Sn/In-, and Te/I-generators and of the self-made Ba/La-generator in industrial tracer experiments are presented. The transfer of the daughter nuclides from the generator eluates into organic phases and the labeling of oil-phases and solid particles are investigated. The developed simple, quick and efficient methods are suitable for routine application under industrial conditions. Some examples of industrial applications of the generator nuclides are given, too.

Considering the nonideal metabolic stability of the difluoro-biphenyl-diarylpyrimidine lead compound I, a series of novel alkylated difluoro-biphenyl-diarylpyrimidines were designed and synthesized based on their structure. Introducing alkyl or substituted alkyl groups on the linker region to block the potential metabolic sensitive sites generated 22 derivatives Among them, compound II with an N-Me group displayed excellent anti-HIV-1 activity and selectivity. The Me group was hopped to the central pyrimidine to occupy the small linker region and maintain the water-mediated hydrogen bond observed in the binding of compound I with RT. The resulting compound III exhibited an improved anti-HIV-1 activity, much lower cytotoxicity, and nanomolar activity toward multiple mutants. In addition, III has a better stability in human liver microsomes than I. Moreover, no apparent in vivo acute toxicity was observed in III-treated female, especially pregnant mice. This series of alkylated compounds with highly potency and safety represent a promising lead template for future discovery.

Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Chemical Communications (Cambridge, United Kingdom) called N-Heterocyclic olefins as efficient phase-transfer catalysts for base-promoted alkylation reactions, Author is Blumel, Marcus; Crocker, Reece D.; Harper, Jason B.; Enders, Dieter; Nguyen, Thanh V., which mentions a compound: 616-14-8, SMILESS is CCC(CI)C, Molecular C5H11I, Category: thiomorpholine.

N-Heterocyclic olefins (NHOs), e.g., I have very recently emerged as efficient promoters for several chem. reactions due to their strong Bronsted/Lewis basicities. The novel application of NHOs as efficient phase-transfer organocatalysts for synthetically important alkylation reactions on a wide range of substrates, further demonstrates the great potential of NHOs in organic chem has been reported.

Author is Zhang, Bi-cheng; Yang, Bo; Liu, Jian; Guan, Sha; Rao, Zhi-guo; Gao, Jian-fei.

Objective To identify the phenotype of tumor-associated macrophages (TAM) in mice bearing Lewis lung carcinoma (LLC). Methods LLC cells were planted in the dorsal necks of C57BL/6 mice s.c. The levels of Th1/Th2 cytokines in the transplantation tumors were tested by ELISA. Co-expression of CD68/macrophage mannose receptor (MMR) and CD68/inducible nitric oxide synthase (iNOS) of TAM was detected by double-labeled immunofluorescence staining. Phagocytic capacity of TAM was assessed by yeast phagocytosis assay. Results In the mice LLC transplantation tumors, Th2 cytokine shift was found in the microenvironment. The concentrations of IFN-γ and IL-12 were (2.19 ±> 0.34) ng/mL and (1635.92 ±> 754.86) ng/mL in transplantation tumors, lower than (5.49 ±> 1.04) ng/mL and (6161.48 ±>498.49) ng/mL in normal lung tissues (P <0.05). IL-4 and IL-10 were (29.31 ±> 14.47) ng/mL and (21.54 ±> 10.72) ng/mL in transplantation tumors, higher than (16.43 ±>6.31) ng/mL and (10.71 ±>2.02) ng/mL in normal lung tissues (P <0.05). The percentage of CD68/MMR(+) TAM in all the TAM was 69.7%-83.2%, while CD68/iNOS (+) was 16.8%-30.3%. The phagocytic rate and index of the transplantation tumors were (5.42 ±> 1.74)% and 0.08 ±>0.02, much lower than (23.63 ±> 5.81)% and 0.39 ±>0.14 in normal spleen tissues with statistical significance (P <0.01). Conclusion TAM in mice bearing LLC might be polarized to the alternative activation phenotype.

Simple, rapid and reproducible stability-indicating methods were established for quant. determination of azathioprine using a, phenomenex 250 mm × 4.9 mm C18, 5 μm, inertsil and UV detection at 240 nm. The isocratic elution was used to quantify the analyte and the mobile phase was acetate buffer: acetonitrile: methanol (30: 35: 35) was pumped at 1.0 mL/min. The method was linear between 10-300 μg/mL, statistically validated for its linearity, precision and accuracy. In this study, degradation behavior of azathioprine was studied by subjecting the drug to various ICH stress conditions. The intra and inter day variation was found to be less than 1% showing high precision of the assay method. It was found that the excipients in the com. tablet did not interfere with the method. Developed method can routinely use for the estimation of azathioprine related compounds from the dosage form and also for stability sample.
