β-Carboline derivatives are potent against Acute Myeloid Leukemia in vitro and in vivo.

Background: β-carboline alkaloids exert a distinguished ability to impair cell growth and induce cell death in a variety of cancers and the evaluation of such new therapeutic candidates may denote new possibilities for leukemia treatment. In this present study, we screened 12 β-carboline derivatives containing different substituents at 1- and 3-positions of β-carboline nucleus for their antineoplastic activities in a panel of leukemia cell lines.

Methods: The cytotoxic effects of the β-carboline derivatives were evaluated in different leukemia cell lines as well as reactive oxygen species (ROS) generation, autophagy, and important signaling pathways.

Potential of Subcritical Water Hydrolysis to Valorize Low-Valued Ray-Finned Fish (): Effects of Hydrolysis Temperature and Pressurization Agent.

Subcritical water (SCW) hydrolysis was applied to valorize the low-valued ray-finned fish () into valuable protein hydrolysates, employing N and CO as pressurization agents at varying temperatures (140, 160, 180, and 200 °C). The degree of hydrolysis (DH) and total free amino acid content increased with temperature for both pressurizing agents. The highest DH (54.

Green fractionation and hydrolysis of fish meal to improve their techno-functional properties.

A green strategy employing water as solvent has been adopted to obtain protein hydrolysates from fish meal (FM), its water-soluble fraction (WSP), and its non-water-soluble fraction (NSP). The techno-functional properties of the hydrolysates have been investigated and compared to hydrolysates obtained with Alcalase®. In general, SWH hydrolysates presented higher content of free amino acids and higher degree of hydrolysis, which reflected on the molecular size distribution.
