Environmentally Benign Bifunctional Solid Acid and Base Catalysts [PDF]

, 2014
Solid bifunctional acid–base catalysts were prepared in two ways on an amorphous silica support: (1) by grafting mercaptopropyl units (followed by oxidation to propylsulfonic acid) and aminopropyl groups to the silica surface (NH2–SiO2–SO3H), and (2) by ...

Solid-phase synthesis for beginners: Choice of tools and techniques for implementation of multistage transformations [PDF]

Russian Journal of General Chemistry, 2010
Several mini-libraries were prepared by solid-phase synthesis: C,N-substituted glycines (1) and 2,5-diaminobenzoic acids (2) using Wang resin as well as diarylthioureas (3) and diaryl-guanidines (4) using Rink resin. Comparative analysis of the instruments and technique for these reactions was provided by applying glass vials with filters (BillBoard ...

IMPDH inhibition enhances cytarabine efficacy in SAMHD1‐expressing leukaemia cells via guanine nucleotide depletion

Molecular Oncology, EarlyView.
Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.
