Introduction: Acute myeloid leukemia (AML) is a rare haematological cancer with poor 5-years overall survival (OS) and high relapse rate. Leukemic cells are sensitive to Natural Killer (NK) cell mediated killing. However, NK cells are highly impaired in AML, which promote AML immune escape from NK cell immune surveillance.

Blood carries some of the most valuable biomarkers for disease screening as it interacts with various tissues and organs in the body. Human blood serum is a reservoir of high molecular weight fraction (HMWF) and low molecular weight fraction (LMWF) proteins. The LMWF proteins are considered disease marker proteins and are often suppressed by HMWF proteins during analysis.

During our efforts to identify biologically active compounds from Red Sea marine invertebrates, a new compound, latrunculin U (), was identified from the Red Sea sponge along with latrunculins A (), B (), and 16--latrunculin B (). The structures of the latrunculins were elucidated based on a combination of comprehensive 1D and 2D NMR analyses and high-resolution mass spectral determinations. The antiproliferative potency of each compound in HeLa cells was evaluated, and they had IC values ranging from 0.

Three new pyridine derivatives, irpelactedines A-C (1-3), and a new furan derivative, irpelactedine D (5), along with two structurally related known compounds, irpexidine A (4) and 5-carboxy-2-furanpropanoic acid (6), were isolated from the medicinal fungus Irpex lacteus SY1002. Their structures were elucidated through NMR and mass spectral analyses, combined with density functional theory calculations of ECD data. Evaluation of angiotensin-converting enzyme (ACE) inhibitory activity revealed that compounds 1 and 3 displayed moderate inhibition, with IC50 values of 31.

When performing effect studies to investigate the impact of microplastic (MP) on cell lines, algae, or daphnia, it is advantageous if such experiments can be performed without the use of surfactants. The need for surfactants arises from the fact that finely milled pristine MP particles generally are hydrophobic. Methods for the preparation of larger amounts of hydrophilic and hence artificially aged MP particles and approaches for their characterization are of high importance.
