Metabolic alterations in human pulmonary artery smooth muscle cells treated with PDGF‐BB

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Metabolic abnormalities are considered to play a key regulatory role in vascular remodeling of pulmonary arterial hypertension. We analyzed the metabolome in the culture supernatants of human pulmonary artery smooth muscle cells (PASMC) during the malignant proliferation phenotype transition via a targeted metabolomics method. Significant and extensive

Mechanisms of base selection by the E.coli mispaired uracil glycosylase [PDF]

open access: yes, 2008
The repair of the multitude of single-base lesions formed daily in the cells of all living organisms is accomplished primarily by the base-excision repair (BER) pathway that initiates repair through a series of lesion-selective glycosylases.

Blocked dihydropteridines as nitric oxide synthase activators [PDF]

open access: yes, 2010
It has been shown that 6-acetyl-7,7-dimethyl-5,6,7,8-tetrahydropteridin-4(3H)-one can act as a competent cofactor for the production of nitric oxide by neuronal nitric oxide synthase (nNOS).

In Plane Vibration of Pyrimidine and some Deuterated Pyrimidines [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 1991
On the basis of 102 assigned frequencies to in plane vibrations of pyrimidine, pyrimidine-2-d2, pyrimidine-2, 5-d2, pyrimidine-4,6-d2, pyrimidine-2,4,6-d3 and pyrimidine-d4, 35 valance force field constants including 14 principals and 21 interaction force constants are calculated.

Electronic structure of the molecule based magnet Cu PM(NO3)2 (H2O)2

open access: yes, 2007
We present density functional calculations on the molecule based S=1/2 antiferromagnetic chain compound Cu PM(NO3)2 (H2O)2; PM = pyrimidine. The properties of the ferro- and antiferromagnetic state are investigated at the level of the local density ...

Mechanochemical Strategies Applied to the Late‐Stage Modifications of Pharmaceutically Active Compounds

open access: yesAngewandte Chemie International Edition, Accepted Article.
This review explores the potential of mechanochemistry in the late‐stage modification of active pharmaceutical ingredients (APIs), offering a comprehensive analysis of methods designed to transform structurally complex molecular scaffolds. By examining the scope, efficiency, and mechanistic aspects of these approaches, the review highlights protocols ...

Three Dimensional Quantitative Structure-Activity Relationships of Sulfonamides Binding Monoclonal Antibody by Comparative Molecular Field Analysis [PDF]

open access: yes, 2008
The three-dimensional quantitative structure-activity relationship (3D-QSAR) model of sulfonamide analogs binding a monoclonal antibody (MabSMR) produced against sulfamerazine, was carried out by comparative molecular field analysis (CoMFA).

Studies on the Physiology of Pyrimidines. The Metabolism of the Pyrimidine Nucleosides

open access: yesExperimental Biology and Medicine, 1929
The results of previous work by one of us1 indicated that the pyrimidines uracil and thymine, when fed in small amounts to dogs, are to a large extent metabolized. In the case of cytosine it was found that this substance was not utilized. It was partly excreted unchanged, partly deaminized and excreted in the form of uracil.These experiments were ...
