Interaction of the 89K murine cytomegalovirus immediate-early protein with core histones [PDF]

open access: yes, 1988
The conditions that permit the interaction of immediate-early proteins of murine cytornegalovirus (MCMV) with DNA were studied. Chromatography of extracts from infected cells on MCMV DNA cellulose and calf thymus DNA cellulose showed that pp89, the ...

Ethnomedicinal Uses, Phytochemistry, Pharmacological Activities, and Toxicology of the Subfamily Gomphrenoideae (Amaranthaceae): A Comprehensive Review

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT The subfamily Gomphrenoideae is composed of about 480 accepted species, many of which have been historically used as medicinal plants, reason why they have been studied in terms of chemical profile, biological activity, and safety. This review consolidates the advances in research on this subfamily over the past 47 years, emphasizing its ...

Purine Chemistry in the Early RNA World at the Origins of Life: From RNA and Nucleobases Lesions to Current Key Metabolic Routes

open access: yesChemBioChem, EarlyView.
In the nascent processes of the beginnings and evolution of life, nucleobases and especially purines, ribonucleos(t)ides and primitive RNAs have been continuously modified. A RNA‐peptide world and key metabolic pathways probably have emerged from the corresponding chemical modifications resulting from adenine deamination, purine alkylation and ...

An Engineered Nonsense \u3cem\u3eURA3\u3c/em\u3e Allele Provides a Versatile System to Detect the Presence, Absence and Appearance of the [em\u3ePSI\u3c/em\u3e\u3csup\u3e+\u3c/sup\u3e] Prion in \u3cem\u3eSaccharomyces cerevisiae\u3c/em\u3e [PDF]

open access: yes, 2006
Common methods to identify yeast cells containing the prion form of the Sup35 translation termination factor, [PSI+], involve a nonsense suppressor phenotype. Decreased function of Sup35p in [PSI+] cells leads to readthrough of certain nonsense mutations

Peptidomimetics Targeting the Amyloidogenicity of Nucleophosmin 1 Mutations in Acute Myeloid Leukemia

open access: yesChemBioChem, Accepted Article.
Nucleophosmin 1(NPM1) is an abundant human protein endowed with many functions whose dysregulation leads to various cancers and mutations are relevant in Acute Myeloid Leukemia (AML). In the wild type form, pentameric NPM1 resides mainly in the nucleolus even if it shuttles toward the cytosol exerting its chaperon function, conversely in AML‐mutated ...

The formation of glycocyamine in animal tissues [PDF]

open access: yes, 1941
It was shown in preceding communications that glycocyamine is converted into creatine by surviving liver slices (1). Our findings indicated that the methylating agent is methionine or a derivative of methionine.

A Simple and Efficient Stereoselective Synthesis of a 2,3‐Difluorosialic Acid‐Based Influenza Virus Neuraminidase Inhibitor

open access: yesChemistry – A European Journal, Volume 31, Issue 16, March 17, 2025.
A new simple approach for the exquisitely stereo‐controlled introduction of the C‐3 equatorial fluorine on neuraminic acid derivatives by incorporation of steric bulk at C‐4. Through this size‐controlled method, we have elaborated a novel synthetic route that exclusively produces the potent anti‐influenza drug candidate; 2,3‐difluoro‐zanamivir analogue

Recent Cutting‐Edge Technologies for the Delivery of Peptide Nucleic Acid

open access: yesChemistry – A European Journal, EarlyView.
This review provides an overview of PNA cellular delivery methods, starting with traditional peptide‐based systems and progressing to advanced approaches using nanoparticles, liposomes, and calixarene. It highlights how these innovative strategies have opened the way for more effective and efficient PNA delivery, ultimately enhancing the potential for ...

Polymerase Synthesis of Hypermodified DNA Displaying a Combination of Thiol, Hydroxyl, Carboxylate, and Imidazole Functional Groups in the Major Groove

open access: yesChemistry – A European Journal, EarlyView.
A series of 2’‐deoxyribonucleoside 5’‐O‐triphosphates bearing functional groups of amino acid side chains in enzyme active sites (OH, SH, COOH, and imidazole) were synthesized and used for enzymatic synthesis of hypermodified DNA displaying these substituents in the major groove mimicking peptides or proteins. Abstract We designed and synthesized a set
