From Heteroaromatic acids and Imines to Azaspirocycles : Stereoselective Synthesis and 3D Shape Analysis [PDF]

open access: yes, 2016
Heteroaromatic carboxylic acids have been directly coupled with imines using T3P and NEt(i-Pr)2 to form azaspirocycles via intermediate N-acyliminium ions.

Synthesis of 2‐Aryl(alkyl)benzimidazole Hydroxamic Acids as HDAC Inhibitors with Anti‐Angiogenesis Properties

open access: yesChemMedChem, Volume 21, Issue 8, 28 April 2026.
2‐Aryl(alkyl)benzimidazole hydroxamic acids (11‐16) are potent and selective HDAC6 inhibitors, with minimal activity against HDAC1/2, and also display anti‐angiogenic and anticancer activities. Compound 13 exhibited a GI50 of 3.9 μM against EPCs and inhibited the growth of HCT‐116, SK‐Hep‐1, and PC‐3 cells with GI50 values of 1.3, 4.2, and 7.5 μM ...

A Novel Approach to Highly Substituted β‐Carbolines via Reductive Ring Transformation of 2‐Acyl‐3‐isoxazolylindoles [PDF]

open access: yes, 2020
We have worked out a new approach to 1,3,4‐trisubstituted β‐carbolines of pharmaceutical interest. As central building blocks we used 2‐acylindoles, which are readily available from indole‐2‐Weinreb amides.

Wherefore the Magic? The Evolutionary Role of Psilocybin in Nature

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
This study explores the evolutionary role of psilocybin, the psychedelic compound found in Psilocybe mushrooms. We provide the first experimental tests of defence and community‐level evidence for invertebrate responses to psilocybin‐producing fungi, revealing significant negative effects on invertebrate locomotion, development, and survival.

Da Yuan Yin Regulates Gut Microbiota and Improves Intestinal Injury in Sepsis

open access: yesFood Science &Nutrition, Volume 14, Issue 4, April 2026.
Sepsis mouse model was induced by LPS to investigate the effect of Da Yuan Yin (DYY) in vivo. Hematoxylin–eosin staining showed that DYY could reduce intestinal injury caused by sepsis. In addition, DYY can also inhibit inflammation, apoptosis, and promote cell proliferation in sepsis, and promote the expression of tight junction proteins.

Development of a Novel, Simultaneous Determination Method for Heterocyclic Amines and Mycotoxins in Fried Food by UPLC–MS/MS Combined With QuEChERS

open access: yesFood Science &Nutrition, Volume 14, Issue 4, April 2026.
• A novel QuEChERS‐UPLC‐MS/MS method was successfully developed for the simultaneous determination of two β‐carboline heterocyclic amines and seven mycotoxins in fried foods. ABSTRACT Dietary exposure to both processing contaminants and natural toxins in fried foods poses a potential health risk, but analytical methods for their simultaneous monitoring

Development of a Bioactive Food Additive for Controlling of Fungal Growth [PDF]

open access: yes, 2017
Fresh foods have a great importance in human nutrition. However, they are marketed with greatly reduced shelf life mainly due to fungal spoilage. In this work, cell wall degrading enzymes produced by Trichoderma asperellum T00 (TCWDE) were immobilized ...

Pd(II)-catalyzed C–H annulation and lactonization of indole-2-carboxamides with hydroxyalkynoates using air as an oxidant

open access: yesTetrahedron Chem
A novel palladium(II) catalyzed C–H annulation strategy has been developed for the synthesis of a diverse range of furo[3′,4':5,6]pyrido[3,4-b]indole-1,5(3H)-dione scaffolds. This is the first report on the construction of polycyclic carboline frameworks
