Disulfide-Bridged Peptides That Mediate Enantioselective Cycloadditions through Thiyl Radical Catalysis

An enantioselective vinylcyclopropane ring-opening/cycloaddition cascade is described. The active thiyl radical catalysts are generated in situ via UV light-promoted homolysis of cystine-based dimers. Amide-functionalization of the peptide at the 4-proline position is essential for effective asymmetric induction. Stereochemical communication is dependent on steric interactions with this substituent that are enforced by H-bonding to the peptide backbone.

Efficient method for the synthesis of functionalized basic maleimides

A three-step procedure involving Diels-Alder condensation of maleic anhydride with furane, formation of N-substituted imide upon reaction with appropriate diamine, and a final retro Diels-Alder regeneration of the maleic carbon-carbon double bond is proposed for an unequivocal synthesis of N-substituted basic maleimides. The novel method is characterized by mild reaction conditions, easy work-up, high yields, and no need for additional catalysis.

Binuclear platinum(II) complexes based on a new bis-bidentate 3,6-di(thien-2-yl)pyridazine skeleton, a novel type of deep-red phosphorescent emitters: Synthesis and nonempirical calculations

Three novel template bis-bidentate ligands based on {3,6-di(thien-2-yl)pyridazine} skeleton and four binuclear Pt(II) complexes containing these metalating templates were synthesized and characterized including photophysical study of two emissive compounds. These complexes display phosphorescence from triplet excited state localized primarily at the thienyl-pyridazine aromatic system, the emission bands being unusually strong shifted (ca. 100 nm/4380 cm?1) to the NIR region compared to analogous phenyl-pyridazine complexes. The absorption and emission characteristics of the complexes were analyzed by using DFT and TD DFT calculations. The results of calculations confirm that emission originates from a mixture of 3LC, 3MLCT, 3LLCT with major contribution of the former excited state and show reasonable agreement with the experimental data.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.SDS of cas: 17057-04-4, you can also check out more blogs about17057-04-4

Synthesis of Five-membered 2-Heteroaryl 2-Heteroaromatic Carboxylates and Attempted Cyclization to Bisheteroaryl[2,3-b:3?2?-d]pyran-2-one

2-Heteroaryl 2-heteroaromatic carboxylates were prepared by reactions of 2-heteroaromatic carbonyl chlorides and 2(5H)-furanone, 2(5H)-thiophenone, and 1-methyl-2(5H)-pyrrolone in triethylamine. The 1H nmr spectra of the esters showed that the electronic effect of both heteroaromatic rings did not cause any sizable shift from each other except for 1-methyl-2-pyrrolyl 1-methyl-2-pyrrolecarboxylate (5c). Attempts to cyclize the esters to heteroaryl-fused pyran-2-ones were unsuccessful. The results may be explained by the most stable conformation of the esters in which two heteroatoms are anti along the C-O bond of the ester group.

Photopolymerization using maleimides as photoinitiators

The photoinitiated polymerization of 1,6-hexanedioldiacrylate (HDDA) has been investigated using a variety of N-substituted maleimides to initiate the polymerization process upon exposure to light from a mercury lamp. When readily abstractable hydrogens are available, the polymerization is rapid. A maleimide with a carbonate group attached gave the greatest exotherm for HDDA polymerization. Copyright

Inhibitors of Protein Kinase C. 1. 2,3-Bisarylmaleimides

The design and synthesis of a series of novel inhibitors of protein kinase C (PKC) is described.These 2,3-bisarylmaleimides were derived from the structural lead provided by the indolocarbazoles, staurosporine and K252a.Optimum activity required the imide NH, both carbonyl groups, and the olefinic bond of the maleimide ring. 2,3-Bisindolylmaleimides were the most active, and the potency of these was improved by a chloro substituent at the 5-position of one indole ring (compound 28, IC50 0.11 muM).In a series of (phenylindolyl)maleimides, nitro compound 74 was most active (IC50 0.67 muM).Naphthalene 19 and benzothiophene 21 showed greater than 100-fold selectivity for inhibition of PKC over the closely related cAMP-dependent protein kinase (PKA).

Inhibitory effect of isoquinoline alkaloids on movement of second-stage larvae of Toxocara canis

To find new anthelmintics against parasites living in host tissues, we used an in vitro assay to screen isoquinoline alkaloids for nematocidal activity on the larva of dog roundworm, Toxocara canis. To evaluate the efficacy of anthelmintics in vitro, Tsuda et al. previously introduced the concept of Relative Mobility (RM) of Toxocara larvae. After improvement of the assay system using image data processing, we generated a new index, RM50, the concentration at which RM = 50%. However, except for pyrantel, the RM 50 of most existing anthelmintics could not be calculated because of low activity. Of the isoquinoline alkaloids tested, emetine, sanguinarine, 6-methoxydihydrosanguinarine (6-MS), chelerythrine and berberine showed strong nematocidal activities. However, these compounds were highly cytotoxic; thus, the prospect of their direct application is low. We then tested the cytotoxicity (IC50) of other isoquinoline alkaloids in HL60 tissue-culture cells. We continued our search for new anthelmintics by examining in detail the relationship between RM50 and IC50. We determined that an ideal target compound would exhibit a low RM50/IC50 ratio. Allocryptopine, dehydrocorydaline and papaverine were identified as potentially effective anthelmintics.
