Thiosialoside clusters using carbosilane dendrimer core scaffolds as a new class of influenza neuraminidase inhibitors.

Jun-Ichi Sakamoto et al.

Bioorganic & medicinal chemistry letters, 17(3), 717-721 (2006-11-11)

An efficient synthesis of a series of carbosilane dendrimers uniformly functionalized with alpha-thioglycoside of sialic acid was accomplished. The results of a preliminary study on biological responses against influenza virus sialidases using thiosialoside clusters showed that some of the glycodendrimers

Metallodynamers: neutral double-dynamic metallosupramolecular polymers.

Cheuk-Fai Chow et al.

Chemistry, an Asian journal, 3(8-9), 1324-1335 (2008-07-30)

Nine neutral dynamic metallosupramolecular polymers (metallodynamers) based on acyl hydrazone derived metal coordination centers (Co(2+), Ni(2+), Zn(2+), and Cd(2+)) were generated through self-assembly polymerization. These are linear coordination polymers with specific optical and mechanical properties. Monomer selection was found to

A stereoselective synthesis of 7 alpha-(3-carboxypropyl) estradiol from a noncontrolled substance.

M Adamczyk et al.

Steroids, 62(12), 771-775 (1998-01-22)

Alkylation of 3,17 beta-bis(2-trimethylsilyl)ethoxymethyl-1,3,5(10) estratriene-6-one (2) with 5-bromo-1-pentene using NaHMDS in THF afforded 3,17 beta-bis(2-trimethylsilyl)ethoxymethyl-7-alpha-(4'pentenyl)-1,3,5(10) estratriene-6-one (3) in excellent stereoselectivity (> 95% epimeric excess). Functionalization of the side chain in compound 3 was accomplished via ozonolysis, oxidation and esterification to

Synthesis, characterization and texture observations of calamitic liquid crystalline compounds.

Maher A Qaddoura et al.

International journal of molecular sciences, 10(11), 4772-4788 (2010-01-21)

Several divinylic mesogenic monomers were synthesized based on coupling the monomer 4-(4-pentenyloxy)benzoic acid with chlorohydroquinone, 2,5-dihydroxy- acetophenone, methylhydroquinone or 2-methoxyhydroquinone. This resulted in novel mesogens of phenylene esters with different lateral substituent groups. The effect of the lateral substituent group

Synthesis of benzophenone-containing fatty acids.

Yonghong Gan et al.

The Journal of organic chemistry, 71(25), 9487-9490 (2006-12-02)

Syntheses of new benzophenone-containing fatty acids (FABPs) 1, 5, and 6 and a new route to FABP 3 are described. Combined with the known 2 and 4, these FABPs comprise a set of photoactivatable fatty acid analogues with the crosslinking

A concise total synthesis of DL-histrionicotoxin.

Maheswaran S Karatholuvhu et al.

Journal of the American Chemical Society, 128(39), 12656-12657 (2006-09-28)

The synthesis of (+/-)-histrionicotoxin has been achieved in just nine steps using a two-directional synthesis strategy. Key reactions include a two-directional cross-metathesis, a tandem oxime formation/Michael addition/1,4-prototopic shift/[3 + 2]-cycloaddition cascade, a selective Z,Z-bisenyne formation, and a one-pot N-O and

Conjugation of bile esters to cellulose by olefin cross-metathesis: A strategy for accessing complex polysaccharide structures.

Yifan Dong et al.

Carbohydrate polymers, 221, 37-47 (2019-06-23)

Bile salts tend to form micelles in aqueous media and can thereby contribute to drug solubilization; they also exhibit crystallization inhibition properties that can stabilize supersaturated drug solutions. Herein, we explore conjugation of bile salts with polysaccharides to create new
