DNA ligases are important enzymes which catalyze the joining of nicks between adjacent bases of double-stranded DNA. NAD+-dependent DNA ligases (LigA) are essential in bacteria and are absent in humans. They have therefore been identified as novel, validated and attractive drug targets. Using virtual screening against an in-house database of compounds and our recently determined crystal structu...

The bifunctional thiourea-tertiary amine derivatives of simple chiral diamines serve as highly enantioselective catalysts for the Michael addition of alpha-substituted cyanoacetates to vinyl sulfones, giving an efficient protocol for the construction of an all-carbon substituted quaternary stereocentre.

A novel method to prepare 2-H-imidazolines from glyoxylic acid monohydrate and 1,2-diamines is described; the key reaction of this method is the oxidative decarboxylation of the 2-carboxy imidazolidines by NBS.

Efficient and continuous monoacylation of symmetrical diamines performed in microreactors yielded superior selectivity to that predicted by statistical considerations. It is highly valuable that the kinetically controlled product in high yields was achieved without any special catalyst at ambient temperature.

The purpose of the present study was to clarify the properties of amine oxidase partially purified from soybean seedlings, which the authors used as an enzyme sample for the assay of diamines (putrescine, cadaverine) and polyamines (spermidine, spermine). The enzyme activity was highest with cadaverine followed by putrescine, spermidine, L7-diaminoheptane and spermine. The optimum pH was 7.8 fo...

Heteroacyclic and Heterocyclic containing drugs showed remarkable and noticeable drug absorption, transmission and drug effects; hence they created their own identity and importance in pharmaceutical, medicinal, agricultural and drug sciences. Thioamido, pyridino, thiobiureto and alkylamino heterocyclic compounds showed various significances and applications in industrial, pharmaceutical, medic...

The use of organophosphorus derivatising agents, prepared from C2 symmetric trimethylsilylated diamines, for the 1H NMR and 31P NMR determination of the enantiomeric composition of chiral alcohols is described.

Template assisted olefin metathesis of an allosteric host to give the corresponding bicyclic compound was achieved and can allosterically bind the template guest diamines, and with different affinity and cooperativity.

In 2004, D-Glucaric acid (GA) was identified as one of the top value-added chemicals from renewable feedstocks. For this study, a patented synthetic method was used to obtain gel forming polymers through the polycondensation of GA and several aliphatic diamines. The first time characterization and a potential practical application of such hydrogels is reported herein. Our findings indicate that...
