Acrosin, a trypsin-like endoprotease, present in the acrosome of spermatozoa, is a promising target for contraceptive agents. Based on the previous homol. modeling and the anal. of the properties of the activity site of human acrosin, a series of 9-substituted-2-amino-6-guanidinopurines were designed and synthesized on a scaffold represented by KF950. The structures of all the title compounds were confined by 1H NMR, MS, IR and elemental anal. Intermediate 5m was determined by single crystal X-ray diffraction anal. The inhibitory activities against acrosin of all target compounds were tested in vitro and all of them exhibited much more inhibitory activities against acrosin, resp., with pos. control, TLCK. Compound 6z exhibited similar inhibitory activities against KF950.

Part II, the main research direction is benzylimidazolylmethylindole preparation antileishmanial agent; indole benzylimidazolylmethyl preparation antileishmanial agent.Formula: C9H11Br.

A new series of 1-benzyl-3-(imidazol-1-ylmethyl)indoles were synthesized according to a previous 3D-QSAR predictive model and assayed for their antiparasitic activity upon Leishmania mexicana promastigotes. The biol. results obtained for these twelve mols. showed an IC50 ranging from 2.3 to 32 μM and mainly illustrated the importance of the hydrophobic parameter in the para-position of the benzyl group. In order to improve the activities of these compounds and to check the potential influence of the electronic parameter on this particular position, a Craig diagram was used to select original electro-donating and lipophilic substituents. Synthesis and biol. evaluation of ten new compounds (IC50 between 2.5 and 5.4 μM) confirmed that only the hydrophobic field is essential for a high level of activity.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 1-(Bromomethyl)-4-ethylbenzene, is researched, Molecular C9H11Br, CAS is 57825-30-6, about Enzyme-Linked Immunosorbent Assay Detection of Pyrrolizidine Alkaloids: Immunogens Based on Quaternary Pyrrolizidinium Salts.SDS of cas: 57825-30-6.

Polyclonal antibody-based enzyme-linked immunosorbent assays (ELISAs) were developed for the detection of retrorsine (1, 351 g/mol), monocrotaline (2, 325 g/mol), and retronecine (3, 155 g/mol) in the ppb range. A set of three bifunctional linking arms was synthesized. By N-alkylation of pyrrolizidine alkaloids (PAs) retrorsine, monocrotaline, and retronecine acetonide, six haptens were synthesized and used to generate rabbit antisera. The resulting anti-retrorsine antiserum gave a 50% inhibition (I50) value of 0.9 ppb for retrorsine with detection limits of 0.5-10 ppb. The same ELISA system also detected isatidine (retrorsine N-oxide) dihydrate (403 g/mol) with an I50 of 1 ppb and senecionine (352 g/mol) with an I50 of 100 ppb. A second monocrotaline-based ELISA detected monocrotaline with an I50 of 36 ppb 2 with detection limits of 5-500 ppb and shows no cross-reactivity with 1 or senecionine; this ELISA demonstrates the potential for the substrate-specific detection method. A third retronecine-based ELISA detects 3 with an I50 of 3000 ppb (3 ppm) and detection limits of 600-10,000 ppb. None of these ELISAs cross-react with the structurally similar swainsonine or lupinine alkaloids. PAs were detected in extracts of Senecio vulgaris and Crotalaria retusa, but not in Lupinus spp., as a demonstration of the ELISA’s usefulness.

Synthetic Route of C9H11Br. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate.

Author is Buendia, Julien; Darses, Benjamin; Dauban, Philippe.

A new tandem C-N and C-C bond-forming reaction has been achieved through RhII/Pd0 catalysis. The sequence combines a catalytic C(sp3)-H nitrene insertion with a palladium-catalyzed C-C cross-coupling to afford complex nitrogenous mols., e.g., I, with very good yields and complete stereoselectivity. The sequence first involves an iodine(III) oxidant, then the in situ generated iodine(I) byproduct is used as a coupling partner. The synthetic value of iodoarenes produced in trivalent iodine reagent mediated oxidations has been demonstrated.

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 1-(Bromomethyl)-4-ethylbenzene(SMILESS: CCC1=CC=C(CBr)C=C1,cas:57825-30-6) is researched.Recommanded Product: 19777-66-3. The article 《Copper(I)-Catalyzed Asymmetric Alkylation of Unsymmetrical Secondary Phosphines》 in relation to this compound, is published in Journal of the American Chemical Society. Let’s take a look at the latest research on this compound (cas:57825-30-6).

A Cu(I)-catalyzed asym. alkylation of HPAr1Ar2 with alkyl halides is uncovered, which provides an array of P-stereogenic phosphines in generally high yield and enantioselectivity. The electrophilic alkyl halides enjoy a broad substrate scope, including allyl bromides, propargyl bromide, benzyl bromides, and alkyl iodides. Also, 11 unsym. diarylphosphines (HPAr1Ar2) serve as competent pronucleophiles. The present methodol. is also successfully applied to catalytic asym. double and triple alkylation, and the corresponding products were obtained in moderate diastereo- and excellent enantioselectivities. Some 31P NMR experiments indicate that bulky HPPhMes exhibits weak competitively coordinating ability to the Cu(I)-bisphosphine complex, and thus the presence of stoichiometric HPAr1Ar2 does not affect the enantioselectivity significantly. Therefore, the high enantioselectivity in this reaction is attributed to the high performance of the unique Cu(I)-(R,RP)-TANIAPHOS complex in asym. induction. Finally, one monophosphine and two bisphosphines prepared by the present reaction are employed as efficient chiral ligands to afford three structurally diversified Cu(I) complexes, which demonstrates the synthetic utility of the present methodol.

A series of novel blue light emitting materials 9,9′-bianthracene derivatives have been designed and synthesized by introducing different substituent groups through Suzuki coupling reactions. Their structure was identified by H NMR and UV-Vis absorption and fluorescence emission; Moreover, their fluorescence quantum efficiency and electrochem. properties were characterized in detail. The results indicate that all these compounds emit blue light, compared with 9,9′-bianthracene, the maximum emission peak of these materials is at 453 nm, red shift of 7 nm, and it is the typical blue fluorescence. This is because these derivatives have a non planar geometric structure. These derivatives also present high fluorescence quantum efficiency and are 1.18-1.43 times as much as that of 9,9′-bianthracene. In addition, their redox actives are also improved. Consequently, it was believed that these derivatives are potential ideal blue light fluorescent materials.
