Protected L-homoDMDP en-8 and its C-6 epimer en-7 were prepared through two different pathways starting from the vinylpyrrolidine en-9. Based on the NMR and X-ray analysis, the stereochemistry of homoDMDP at C-6 was confirmed to be consistent with reported data. Compounds en-7 and en-8 are general intermediates for the synthesis of a series of 6-C-alkylated DMDP-related natural products, such a...

background: volatile organic compounds (vocs) are among the main air pollutants which have destructive effects on the environment and human health. considering the carcinogenic effects of some of these compounds including benzene, how to control and limit them is considered an important issue in environmental research. the aim of this study was to evaluate the use of the combined ultraviolet (u...

To probe the molecular interactions of factor XI we have prepared two monoclonal antibodies (MoAbs; 5F7 and 3C1), each of which binds the heavy chain of reduced and alkylated factor XIa. Competitive solid phase radioimmunoassay (RIA) binding studies revealed that 5F7 and 3C1 are directed against different epitopes within factor XI. One antibody (5F7) blocked the surface-mediated proteolytic act...

Immunoglobulins were isolated from the surfaces of lymphocytes from a variety of lymphocyte populations including murine and human thymus lymphocytes and murine spleen and thoracic duct lymphocytes. Cell surface proteins were labeled with iodide-(125)I by lactoperoxidase-catalyzed iodination, and recovered in solution either by solubilization in dissociating solvents or active metabolic release...

a number of 3-amino-1, 2, 4-triazin-5 (2h)- ones(1) were synthesized and condensed with a-haloketones to give 2,6-disubstituted imidazo [1, 2-b] [1, 2, 4]-triazin-3 (4h)-ones (2). these compounds were reacted further with a - haloketones to yield n-alkylated products (3).

The open-circuit voltage and efficiency of PM6:DTY6 solar cells processed from o -xylene is increased by adding alkylated Y-series acceptors as the third component.

this paper focuses on the effects of the addition of an ionic liquid, 1-allyl-3-butylimidazilium bis(trifluoromethane sulfonyl)imide ([abim]tfsi), which has a high affinity for benzene, into the poly(vinyl chloride) (pvc) membrane on the pervaporation characteristics of the removal of benzene from aqueous solutions of dilute benzene. when aqueous solutions of 100～500 ppm benzene were permeated ...

The chemical relations among Bence-Jones proteins, myeloma proteins, and normal gamma-globulins have been investigated by a variety of means. Starch gel electrophoresis in 8 M urea of reduced alkylated Bence-Jones proteins yielded patterns of bands corresponding to those of the light (L) polypeptide chains of the dissociated myeloma protein from the same patient. One instance in which this corr...

An effective hydrophobization of ionic carbon nitride (PHI) nanoparticles in the form a composite with alkylated silica enables highly efficient photocatalysts for light-driven production hydrogen peroxide under biphasic conditions.

the conformational behavior of monosubstituted tri-methylsilyle ethynyl derivative of cal ix[4]arene as a newgeneration of caliarene was compared with tetra alkylated calyx[4]arene. the most important conformationalphenomena in these compounds which are pinched cone interconversion process were done by semi-empiricalmethod and ab initio calculations with gaussian 98w programming.
