Leukemia and Benzene [PDF]

International Journal of Environmental Research and Public Health, 2012
Excessive exposure to benzene has been known for more than a century to damage the bone marrow resulting in decreases in the numbers of circulating blood cells, and ultimately, aplastic anemia. Of more recent vintage has been the appreciation that an alternative outcome of benzene exposure has been the development of one or more types of leukemia ...

Scientific opinion on the assessment of the exposure of the population of the republic of Croatia to delta‐9‐tetrahydrocanabinol (δ9‐thc) from industrial hemp food on the market of the republic of Croatia

Food Risk Assess Europe, Volume 3, Issue 4, October 2025.
Summary Delta‐9‐tetrahydrocannabinol (Δ9‐THC) is a naturally occurring psychoactive compound derived from the hemp plant Cannabis sativa. In 2015, EFSA established an acute reference dose (ARfD) of 1 μg/kg body weight (bw) for Δ9‐THC and assessed acute dietary exposure from milk and dairy products.

Scientific report on the determination of the presence of cannabinoids in industrial hemp food on the market of the Republic of Croatia

Food Risk Assess Europe, Volume 3, Issue 4, October 2025.
Summary Cannabis sativa L. is one of the oldest cultivated plants on the planet. It was initially used by humans as a source of roughage for animals and as a textile fiber; over time, it has been used as a source of food and medicine. The plant contains bioactive compounds called cannabinoids. The best‐known cannabinoids occurring in Cannabis sativa L.

Recent Insights in Multi‐Target Drugs in Pharmacology and Medicinal Chemistry

ChemMedChem, Volume 20, Issue 18, September 25, 2025.
This review highlights the rationale behind multitarget drug design as a promising approach to address diseases with complex etiologies. By combining pharmacophore features from different single‐target drugs, multitarget compounds can interact with multiple biological targets simultaneously.

Verständnis und Optimierung der Singulett‐Triplett‐(S1/T1)‐Energiedifferenzen in planaren organischen Chromophoren

Angewandte Chemie, Volume 137, Issue 21, May 19, 2025.
Ein neues Modell zur Optimierung der Singulett‐Triplett‐(S1/T1)‐Energiedifferenzen wurde entwickelt, das auf elektrostatischen Wechselwirkungen der Übergangsdichte basiert. Drei klar anwendbare Regeln zur Maximierung der Singulett‐Triplett‐Energiedifferenzen werden abgeleitet: Minimierung der Gesamtzahl an π‐Elektronen, Lokalisierung der π‐Elektronen ...

Heavier Benzene‐1,4‐diides: Merging Aromatics and Metallylenes

European Journal of Inorganic Chemistry, Volume 28, Issue 12, April 17, 2025.
A conceptually new type of Group 14 compounds [(ADC)E]2 based on anionic dicarbene (ADC) scaffolds have been reviewed. The Group 14 elements in the planar C4E2 ring of [(ADC)E]2 are formally in +1 oxidation state; each has a σ‐type lone‐pair and an unpaired electron in the π‐type orbital.

Cyclische Acetale als expandierende Monomer zur Verringerung von Schrumpfung

Angewandte Chemie, Volume 136, Issue 51, December 16, 2024.
Der Van‐der‐Waals‐Abstand zwischen einem Thiol und einem Alken ist abgebildet. Nach der Thiol‐En‐Reaktion wird eine Thioetherbindung gebildet, die zu einem kürzeren interatomaren Abstand führt. Diese Schrumpfung führt zu Spannungen im Polymer, die durch radikalvermittelte Redox‐Umlagerungen, katalysiert mittels eines Thiols, reduziert werden können ...

Die Azid‐Wittig Reaktion

Angewandte Chemie, Volume 136, Issue 50, December 9, 2024.
Mehr als 100 Jahre nach Staudingers Berichten über die Reaktion von Iminophosphoranen mit Aldehyden wurde ein alternativer Weg, die sogenannte „Azid‐Wittig‐Reaktion“, entdeckt. Wir beschreiben die Reaktion von Aziden mit PMe3 in Gegenwart von aromatischen Aldehyden, um Triazabutadiene (TBDs) zu erhalten.
