A new 3,4-secodammarane derivative () was obtained from the bark of . The combination of spectral analysis and the computation of electronic circular dichroism (ECD) has definitively confirmed the absolute configuration of the compound. This configuration has been identified as methyl (20S, 24 R)-epoxy-25-hydroxy-3,4-secodammar-4(28)-en-29-al-3-oate. Furthermore, Compound exhibited notable inhibitory effects on two specific cancer cell lines: the MDA-MB-231 and the SW620. The calculated IC values for these cell lines were found to be 23.02 and 20.88 μM, respectively, indicating a significant potential for this compound in therapeutic applications against these types of cancer.

Three antileishmanial compounds incorporating a butylated hydroxytoluene (BHT) moiety and an acrylate-based Michael acceptor scaffold were rationally designed from the lead structures LQFM064 and LQFM332, which feature a chalcone-derived core. Their activities against Leishmania (L.) amazonensis were evaluated.

Background: Glucocorticoids remain the primary treatment for acute lymphoblastic leukemia (ALL) in children. However, glucocorticoid-resistant ALL exhibits increased mortality rates. To overcome resistance and improve management strategies, alternative therapeutic agents are required.

This study investigates the HO and CO sorption behavior of two chemically distinct polystyrene-divinylbenzene-based ion exchange sorbents: a primary amine and a permanently charged strong base quaternary ammonium (QA) group with (bi)carbonate counter anions. We compare their distinct interactions with HO and CO through simultaneous thermal gravimetric, calorimetric, gas analysis, and molecular modeling approaches to evaluate their performance for dilute CO separations like direct air capture. Thermal and hybrid (heat + low-temperature hydration) desorption experiments demonstrate that the QA-based sorbent binds both water and CO more strongly than the amine counterparts but undergoes degradation at moderate temperatures, limiting its compatibility with thermal swing regeneration.

Plant biomass has emerged as a cornerstone of the global bioenergy landscape because of its abundance and cost-effectiveness. The cell wall of plant biomass is an intricate network of cellulose, hemicellulose, and lignin. The hydrolysis of cellulose and hemicellulose by holoenzymes converts these polymers into monosaccharides and paves the way for the production of bioethanol and other bio-based products.

Background: Sarcomas are rare cancer with a heterogeneous group of tumors. They affect both genders across all age groups and present significant heterogeneity, with more than 70 histological subtypes. Despite tailored treatments, the high metastatic potential of sarcomas remains a major factor in poor patient survival, as metastasis is often the leading cause of death.
