A Polyamine-Based Dinitro-Naphthalimide Conjugate as Substrates for Polyamine Transporters Preferentially Accumulates in Cancer Cells and Minimizes Side Effects in vitro and in vivo

open access: yesFrontiers in Chemistry, 2020
Naphthalimides, such as amonafide and mitonafide in clinical trials, have been developed as antitumor agents for orthotopic tumor. However, the serious side effects in cancer patients limit their applications.

Exogén SA kezelések fényben és sötétben történő hatásának összehasonlító elemzése vad típusú és etilén receptor mutáns, Never-ripe paradicsom növények leveleiben [PDF]

open access: yes, 2018
Biotic stresses is caused in plants due to damage instigated by other organisms, like insects, disease (fungal, bacterial, and viral), which are major limitations to crop yield. The cellular response to biotic stress is an oxidative and nitrosative burst

Bis(benzyl)polyamine analogs as novel substrates for polyamine oxidase.

open access: yesJournal of Biological Chemistry, 1990
N,N'-Bis(benzyl)polyamine analogs were found to be substrates for highly purified polyamine oxidase. Metabolism of these analogs was apparently dependent on molecular O2 and resulted in the formation of benzaldehyde, H2O2, and a polyamine analog with free terminal amines.

Weight Loss During Obesity Provokes Asparaginase‐Associated Liver Steatosis and Endoplasmic Reticulum Stress

open access: yesThe FASEB Journal, Volume 40, Issue 6, 31 March 2026.
Lean mice and DIO mice were fed either a low‐fat maintenance diet (MD) or a high‐fat obesogenic diet (OD) during pegylated asparaginase exposure. OD exacerbated asparaginase‐induced weight loss and modestly increased liver triglycerides and ER stress in lean mice.

Application of sucrose modulates the expressions of genes involved in proline and polyamine metabolism in maize seedlings exposed to drought

open access: yesBiologia Plantarum, 2019
Sucrose, proline, and polyamines are compatible solutes accumulating in plant tissues and increasing cellular osmolarity under environmental stresses. These compatible solutes and hydrogen peroxide can function as signaling molecules in plants. There has

NF-E2-related factor 1 suppresses the expression of a spermine oxidase and the production of highly reactive acrolein

open access: yesScientific Reports
Polyamines (putrescine, spermidine, and spermine) are among the most abundant intracellular small molecular metabolites, with concentrations at the mM level. The ratios of these three molecules remain constant under physiological conditions. Stress (i.e.
