Organic multicomponent microparticle libraries

The Generation of Dihydropyrimidine Libraries Utilizing Biginelli Multicomponent Chemistry

With the emergence of high-throughput screening in the pharmaceutical industry over a decade ago, synthetic chemists were faced with the challenge of preparing large collections of molecules to satisfy the demand for new screening compounds. The unique exploratory power of multicomponent reactions such as the Ugi four-component reaction was soon recognized to be extremely valuable to produce co...

One pot synthesis of selenocysteine containing peptoid libraries by Ugi multicomponent reactions in water.

Selenocysteine containing peptoids and peptide-peptoid conjugates were synthesized by combinatorial Ugi-MCRs (multicomponent reactions) in water: for the first time, an acetal (selenoacetal 2a) was used in Ugi-MCR to furnish selenocysteine peptoids in one step as model compounds for selenocysteine peptides and proteins.

Chemistry of the isocyanides and their multicomponent reactions , including their libraries – the initiatives of Ivar Ugi

The platelet microparticle proteome.

Platelet-derived microparticles are the most abundant type of microparticle in human blood and contribute to many biologically significant processes. Here, we report the first proteomic analysis of microparticles generated from activated platelets. Using 1D SDS-PAGE and liquid chromatography coupled to a linear ion trap mass spectrometer, the identification of 578 proteins was accomplished usin...

Electro-Organic Synthesis: An Efficient Method for the Preparation of Nanosized Particles of Phthalazine Derivatives via One-Pot Multicomponent Reactions

Aza heterocyclic compounds are major interest for organic chemists because of their mainly pharmacological activities and clinical applications such as antianxiety, antitumor, anticonvulsant, cardiotonic and vasorelaxant. This contribution describes an electrochemical approach for the preparation of nanosized particles of phthalazine in high yields and very short reaction time. The method is ba...
