A new mechanistic insight of DNA base adenine formation from pentamer HCN in the gas phase of interstellar clouds

open access: yesJournal of Taibah University for Science, 2019
The mechanism formation of adenine is determinate in the gas phase, by using density functional theory (DFT) method at the B3LYP hybrid together with 6-311g(d,p) basis set level. Thus, we have investigated the structures and mechanisms pathway as well as

Adenine decreases hypertrophic effects through interleukin-18 receptor

open access: yesChinese Journal of Physiology, 2019
Cardiac hypertrophy is the main cause of heart failure. Levels of circulating interleukin-18 (IL-18) have been reported to increase in congestive heart disease and cardiac hypertrophy. Relationships among IL-18 levels, IL-18 receptor (IL-18R) expression,

(1RS,2RS,6RS)-2-(6-Amino-9H-purin-9-yl)-8-azaspiro[5.6]dodec-10-en-1-ol Dihydrochloride

open access: yesMolbank, 2022
The title compound (1RS,2RS,6RS)-2-(6-Amino-9H-purin-9-yl)-8-azaspiro[5.6]dodec-10-en-1-ol dihydrochloride was synthesized for the first time in two steps, the first of which was a regioselectivity of epoxide ring-opening reaction under the action of ...

Mutations in valosin-containing protein (VCP) decrease ADP/ATP translocation across the mitochondrial membrane and impair energy metabolism in human neurons [PDF]

open access: yes, 2017
Mutations in the gene encoding valosin-containing protein (VCP) lead to multisystem proteinopathies including frontotemporal dementia. We have previously shown that patient-derived VCP mutant fibroblasts exhibit lower mitochondrial membrane potential ...

The Dissipative Photochemical Origin of Life: UVC Abiogenesis of Adenine

open access: yesEntropy, 2021
The non-equilibrium thermodynamics and the photochemical reaction mechanisms are described which may have been involved in the dissipative structuring, proliferation and complexation of the fundamental molecules of life from simpler and more common ...

Infrared Spectral Signatures of Nucleobases in Interstellar Ices I: Purines

open access: yesLife, 2023
The purine nucleobases adenine and guanine are complex organic molecules that are essential for life. Despite their ubiquitous presence on Earth, purines have yet to be detected in observations of astronomical environments.

RETRACTED: Adenine Combined with Cisplatin Promotes Anticancer Activity against Hepatocellular Cancer Cells through AMPK-Mediated p53/p21 and p38 MAPK Cascades

open access: yesPharmaceuticals, 2022
Cisplatin has been widely used in cancer treatments. Recent evidence indicates that adenine has potential anticancer activities against various types of cancers. However, the effects of the combination of adenine and cisplatin on hepatocellular carcinoma

The Role of Organic Peroxides in the Induction of Mutations [PDF]

open access: yes, 1949
The discovery by Wyss, Stone, and Clark' that bacteria grown on a substrate recently exposed to ultra-violet light are subject to high mutation rates shows clearly that some meta-stable chemical substance, probably of no great complexity, is an ...

Mutual Relations between Substituent Effect, Hydrogen Bonding, and Aromaticity in Adenine-Uracil and Adenine-Adenine Base Pairs

open access: yesMolecules, 2020
The electronic structure of substituted molecules is governed, to a significant extent, by the substituent effect (SE). In this paper, SEs in selected nucleic acid base pairs (Watson-Crick, Hoogsteen, adenine-adenine) are analyzed, with special emphasis ...

Mechanism study on the effect of adenine on the viability of Lactiplantibacillus plantarum LIP-1 powder via freeze-drying

open access: yesFood Science of Animal Products, 2023
Adenine acts as a growth promoter to promote the growth of the lactic acid bacteria (LAB), but the effect on the viability of freeze-dried strains has rarely been studied.
