Radioaetive leueine was ineorporated by N eurospora crassa mitoehondria in vivo in the presence of cyeloheximide. When the membrane protein of these mitochondria was ehromatographieally separated on oleyl polymethaerylie aeid resin, & nurober of fraetions were obtained whieh differ with respeet to their eontents of radioaetivity and eytoehromes. The highest speeifie radioaetivity was found in t...

Cationic lipids constitute a family of synthetic vectors commonly used for nucleic acids delivery. We herein report the results of a systematic study that aimed to compare the transfection efficacies of cationic lipophosphoramidates possessing either two identical lipid chains (termed symmetric cationic lipids) or two different lipid chains (non-symmetric cationic lipids). In addition, we also ...

We present a lattice model for helicity induction on an optically inactive polymer due to the adsorption of exogenous chiral amine molecules. The system is mapped onto a one-dimensional Ising model characterized by an on-site polymer helicity variable and an amine occupancy one. The equilibrium properties are analyzed in the limits of strong coupling between helicity induction and amine adsorpt...

The non-H atoms in the structure of the title mol-ecule, C7H7N3, are almost coplanar (r.m.s. deviation = 0.018 Å). The two amine groups each donate two and accept one weak N-H⋯N hydrogen bonds. N-H⋯N hydrogen bonding between the amine and nitrile groups results in chains parallel to [101] in the crystal structure. The chains are cross-linked by N-H⋯N hydrogen bonds between amine groups, giving ...

We report in this communication the facile synthesis of the new tris(thiazolylmethyl)amine TTA ligand and the full characterization in solution and in the solid state of two ferrous complexes, [(TTA)FeCl2] and [(TTA)Fe(OTf)2]. TTA, the first example of a simple tris(thiazolemethyl)amine chelate--the second one only within this class of tripods--exerts a weak ligand field and the tertiary amine ...

    Topical drug dosage forms such as ointments and creams can be easily removed through wetting, movement and contact. The new bioadhesive formulations with enhanced local anesthetic effects are needed for topical administration. The adhesive capacity of hydroxypropyl methylcellulose (HPMC) was determined by measuring the maximum detachment force and the adhesion work with an auto peeling test...

We demonstrate Ni–N/C is an effective electrocatalyst for the direct conversion of captured CO 2 in monoethanol amine-based aqueous absorbents showing high faradaic efficiency (78%) and its selectivity maintained various amine solvents.

The thio-amide and quaternary amine parts of the title compound, C(6)H(15)N(2)S(+)·Cl(-), are mutually almost perpendicular, the dihedral angle being 80.6 (7)°. The thio-amide group is planar and adopts a Z conformation, whereas the amine end of the cation is in an extended conformation. In the supra-molecular structure, mol-ecules are linked into centrosymmetric dimers by two hydrogen bonds: N...
