The synthesis of a series of novel 4-substituted 2,3,6,7-tetrahydrobenzo [1,2-b;4,5-b?]difuran?1H-imidazolium salts is presented. The biological properties of the compounds were evaluated in vitro against a panel of human tumor cell lines. Results suggest that the 5,6-dimethyl-benzimidazole or 2-methyl-benzimidazole ring, and substitution of the imidazolyl-3-position with a 2-naphthylmethyl substituent or 2-naphthylacyl substituent, were important to the cytotoxic activity. Notably, 3-(2-Naphthylmethyl)-1-((2,3,6,7-tetrahydrobenzo[1,2-b;4,5-b?]difuran-4-yl)methyl)-1H-5,6-dimethyl-benzimidazol-3-ium bromide (42) was found to be the most potent derivative against five human tumor cell lines with IC50 values of 1.06?4.34 muM and more selective towards SMMC-7721, A549 and SW480 cell lines. 3-(2-Naphthylacyl)-1-((2,3,6,7-tetrahydrobenzo[1,2-b;4,5-b?]difuran-4-yl)methyl)-1H-2-methyl-benzimidazol-3-ium bromide (37) showed higher selectivity to SMMC-7721 and MCF-7 cell lines with IC50 values 2.7-fold and 8.4-fold lower than DDP. Study regarding to the antitumor mechanism of action showed that compound 37 could induce cell cycle G1 phase arrest and apoptosis in SMMC-7721 cells.

A simple procedure was developed for the monoacylation of several unprotected alkanediamines with carboxylic acids by using PyBOP-HOBt as coupling agent in the presence of DIEA at room temperature. Yields were moderate with primary alkanediamines and good to excellent with linear or cyclic secondary ones. To illustrate the utility of these monoacylated products, six unsymmetrical diacylated alkanediamines were synthesized. In addition, one of these compounds was evaluated as organocatalyst in an asymmetric aldol reaction.

Synthetic Route of 22013-33-8, In a article, mentioned the application of 22013-33-8, Name is 2,3-Dihydrobenzo[b][1,4]dioxin-6-amine, molecular formula is C8H9NO2

Chiral biphenols catalyze the asymmetric Petasis borono-Mannich allylation of aldehydes and amines through the use of a bench-stable allyldioxaborolane. The reaction proceeds via a two-step, one-pot process and requires 2?8 mole % of 3,3?-Ph2-BINOL as the optimal catalyst. Under microwave heating the reaction affords chiral homoallylic amines in excellent yields (up to 99 %) and high enantioselectivies (er up to 99:1). The catalytic reaction is a true multicomponent condensation reaction whereas both the aldehyde and the amine can possess a wide range of structural and electronic properties. Use of crotyldioxaborolane in the reaction results in stereodivergent products with anti- and syn-diastereomers both in good diastereoselectivities and enantioselectivities from the corresponding E- and Z-borolane stereoisomers.

The catalyzed pathway has a lower Ea, but the net change in energy that results from the reaction is not affected by the presence of a catalyst. In my other articles, you can also check out more blogs about 22013-33-8

Human acrosin is a promising target for male contraceptives. A series of novel guanidinophenylpyrazole derivatives were rationally designed by molecular hybridization of the phenylpyrazole and guanidinobenzoate inhibitors. Most of the target compounds showed potent human acrosin inhibitory activities. In particular, compound F3 was a highly active human acrosin inhibitor (IC50 = 1.26 muM) with good selectivity over trypsin. Molecular docking studies revealed that compound F3 formed hydrophobic and hydrogen bonding interactions with the active site of human acrosin. Compound F3 represents a promising lead compound for the development of novel male contraceptives.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms.In my other articles, you can also check out more blogs about 22013-33-8COA of Formula: C8H9NO2.

Electric Literature of 2879-20-1, While the job of a research scientist varies, most chemistry careers in research are based in laboratories, where research is conducted by teams following scientific methods and standards. In a document type is Article, and a compound is mentioned, 2879-20-1, Name is 1-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)ethanone, introducing its new discovery.

The fungal plasma membrane H+-ATPase (Pma1p) is a potential target for the discovery of new antifungal agents. Surprisingly, no structure?activity relationship studies for small molecules targeting Pma1p have been reported. Herein, we disclose a LEGO-inspired fragment assembly strategy for the design, synthesis, and discovery of benzo[d]thiazoles containing a 3,4-dihydroxyphenyl moiety as potential Pma1p inhibitors. A series of 2-(benzo[d]thiazol-2-ylthio)-1-(3,4-dihydroxyphenyl)ethanones was found to inhibit Pma1p, with the most potent IC50 value of 8 mum in an in vitro plasma membrane H+-ATPase assay. These compounds were also found to strongly inhibit the action of proton pumping when Pma1p was reconstituted into liposomes. 1-(3,4-Dihydroxyphenyl)-2-((6-(trifluoromethyl)benzo[d]thiazol-2-yl)thio)ethan-1-one (compound 38) showed inhibitory activities on the growth of Candida albicans and Saccharomyces cerevisiae, which could be correlated and substantiated with the ability to inhibit Pma1p in vitro.

Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.Read on for other articles about 2879-20-1Electric Literature of 2879-20-1“.
