Assessing Popper Purity—Implications for the Regulation and Recreational Use of Alkyl Nitrites

Psychoactives
Alkyl nitrites (“poppers”) are a diverse class of volatile chemical compounds with a varied legal and medical history. Though once commonly prescribed to treat angina, popper use is now almost exclusively recreational.

Decoding nitrogen uptake efficiency in maize and sorghum: insights from comparative gene regulatory networks

The Plant Journal, Volume 124, Issue 6, December 2025.
Significance Statement To decipher the regulatory basis of nitrogen, use efficiency (NUE), we built maize‐ and sorghum‐specific gene regulatory networks (GRNs). Cross‐species analyses revealed conserved and species‐specific feed‐forward loops (FFLs), with bZIP18 and bZIP30 as key regulators in maize.

Erectile Dysfunction in Diabetes Mellitus: A Comprehensive Narrative Review of Pathophysiology, Genetic Association Studies and Therapeutic Approaches

Endocrinology, Diabetes &Metabolism, Volume 8, Issue 5, September 2025.
Interplay between erectile dysfunction, diabetes mellitus and genetics. ABSTRACT Introduction Erectile dysfunction (ED) is a highly prevalent complication of diabetes mellitus (DM), significantly impairing quality of life and psychosocial well‐being. The prevalence of ED is estimated to be over 3.5 times higher in men with diabetes mellitus compared to

The nitrite anion: the key intermediate in alkyl nitrates degradative mechanism. [PDF]

, 2007
Alkyl nitrates, _in vivo_, are metabolized to yield nitric oxide, and thiol groups are considered necessary cofactors. This statement is based on studies that underline how these species potentiate hemodynamic responsiveness to nitrates in patients with ...

A remarkably simple α-oximation of ketones to 1,2-dione monooximes using the chlorotrimethylsilane-isoamyl nitrite combination [PDF]

, 2003
Ketones undergo α-oximation by NOCl formed in situ from Me3SiCl and isoamyl nitrite, either in solution or under solvent-free conditions, to produce 1,2-dione monooximes in excellent yields. The oximation is regiospecific in appropriate cases.

Expedient Access to 18F‐Fluoroheteroarenes via Deaminative Radiofluorination of Aniline‐Derived Pyridinium Salts

Angewandte Chemie, Volume 136, Issue 26, June 21, 2024.
18F‐Fluoroheteroarenes find wide application as radiotracers for PET (positron emission tomography) imaging. Here, we present a deaminative radiosynthetic approach via pyridinium tetrafluoroborates that facilitates radiofluorination of 33 structurally diverse heteroarenes in up to 98 % RCY (radiochemical yield).
