Bosch E.
PMID: 27703122
Acta Crystallogr C Struct Chem. 2016 Oct 01;72:748-752. doi: 10.1107/S2053229616014972. Epub 2016 Sep 26.

Weak interactions between organic molecules are important in solid-state structures where the sum of the weaker interactions support the overall three-dimensional crystal structure. The sp-C-H...N hydrogen-bonding interaction is strong enough to promote the deliberate cocrystallization of a series of...

Diabetes Metab Syndr Obes. 2017 Jun 07;10:207-222. doi: 10.2147/DMSO.S132537. eCollection 2017.

BACKGROUND: Sitagliptin, a dipeptidyl peptidase-4 (DPP-4) inhibitor used in type 2 diabetes therapy, has demonstrated protective effects in diabetic chronic kidney disease, in part due to its pleiotropic actions. However, its potential direct effects on the kidney are still...

Prefrontal inputs to the amygdala instruct fear extinction memory formation.

Sci Adv. 2015 Jul;1(6). doi: 10.1126/sciadv.1500251. Epub 2015 Jul 31.

Persistent anxiety after a psychological trauma is a hallmark of many anxiety disorders. However, the neural circuits mediating the extinction of traumatic fear memories remain incompletely understood. We show that selective, in vivo stimulation of the ventromedial prefrontal cortex...

One- and two-dimensional silver-coordination networks containing pi-sandwiched silver-silver interactions.

Inorganic chemistry

Bosch E, Barnes CL.
PMID: 11978124
Inorg Chem. 2002 May 06;41(9):2543-7. doi: 10.1021/ic010795q.

The self-assembly of coordination networks from reaction of 2,4,6-trimesityl-1,3,5-triazine and silver(I) trifluoroacetate is described. A one-dimensional linear polymer is formed from solutions deficient in silver while a two-dimensional, graphite-like sheet is formed from solutions containing 3 equiv of silver...

Inorg Chem. 2001 Jun 18;40(13):3097-100. doi: 10.1021/ic010058u.

The design, synthesis, and complexation characteristics of the bipyridyl ligand 1,2-bis-(2-pyridylethynyl)benzene are described. The X-ray crystallographic characterization of the 1:1 complexes of 1,2-bis(2-pyridylethynyl)benzene with silver(I) triflate and palladium(II) chloride are described. In the X-ray crystal structure of the silver(I)...

A QSPR study of the p solute polarity parameter to estimate retention in HPLC.

Journal of chemical information and computer sciences

PMID: 12870917
J Chem Inf Comput Sci. 2003 Jul-Aug;43(4):1240-7. doi: 10.1021/ci0340660.

A Quantitative Structure-Property Relationship (QSPR) model is developed to calculate the solute polarity parameter p of a set of 233 compounds of a very different chemical nature. The proposed model, derived from multiple linear regression, contains four descriptors calculated...
