Article Abstract
A series of new analogs based on the structure of lead compound 10 were designed, synthesized and evaluated for their in vitro anti-cancer activities against four selected human cancer cell lines (HL-60, Bel-7402, SK-BR-3 and MDA-MB-468). Several synthesized compounds exhibited improved anti-cancer activities comparing with lead compound 10. Among them, 1,3,4-oxadiazole analogs 17o showed highest bioactivity with IC50 values of 1.23, 0.58 and 4.29 μM against Bel-7402, SK-BR-3 and MDA-MB-468 cells, respectively. It is noteworthy that 17o has potent anti-proliferation activity toward a panel of cancer cells with relatively less cytotoxicity to nonmalignant cells. The further mechanistic study showed that it induced apoptosis and cell cycle arrest through disrupting spindle assembly in mitotic progression, indicating these synthesized dithiocarbamates represented a novel series of anti-cancer compounds targeting mitosis.

Background: Innovative antibiotic discovery strategies are urgently needed to successfully combat infections caused by multi-drug-resistant bacteria.
Methods: We employed a direct screening approach to identify compounds with antimicrobial and antimicrobial helper-drug activity against Gram-positive and Gram-negative bacteria. We used this platform in two different strains of methicillin-resistant (MRSA) and aminoglycoside-resistant strains of to screen for antimicrobials compounds, which potentiate the activity of aminoglycoside antibiotics.
Comprehensive DFT and SCAPS-1D Study of Structural, Electronic, Optical, Mechanical, Phonon, Thermoelectric, and Photovoltaic Properties of Lead-Free ZBrO (Z = K, Rb, Cs, and Fr) Anti-Perovskites.

This study presents a comprehensive first-principles and device-performance investigation of alkali metal-based anti-perovskites ZBrO (Z = K, Rb, Cs, and Fr) for advanced optoelectronic and photovoltaic applications. Using density functional theory (DFT) with GGA-PBE and mGGA-rSCAN functionals, we analyzed the structural, electronic, optical, mechanical, phonon, population, and thermoelectric properties of these compounds. All ZBrO materials exhibit direct band gaps and strong optical absorption in the visible-UV spectrum.

Paraptosis is a distinct form of programmed cell death characterized by cytoplasmic vacuolization, mitochondrial swelling, and endoplasmic reticulum (ER) dilation, offering an alternative to apoptosis for therapeutic applications. In this study, we identified a hemicyanine derivative that is a potent paraptosis inducer in two cancer cell lines. This compound triggers hallmark paraptotic features, including ER swelling, mitochondrial morphological changes, increased superoxide production, and caspase-independent cell death.

Insect chemoreception is essential for locating food, selecting oviposition sites, and detecting infochemicals. In tephritid fruit flies, chemosensory perception occurs primarily through sensilla on the antennal flagella, maxillary palps, and ovipositor. Identifying these sensilla provides insights into olfaction, which may lead to improvements in insect control measures.

Asiatic acid (AA) was used as the lead compound and 22 inhibitors of specificity protein 1 (Sp1) were designed and synthesized with modification at A ring and C-28 position of AA, whose structures were confirmed by HRMS, H NMR and C NMR. The growth inhibitory effects of Asiatic acid derivatives on human breast cancer cells (MCF-7) and cervical cancer cells (Hela) were determined by tetramethyl azole salt (3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, MTT) colorimetric assay. The results showed that all of these compounds inhibited the proliferation of HeLa and MCF-7 cells, and all the derivatives showed stronger tumor cytotoxicity than AA, among which compounds I, II, and III were comparable to the positive control drug cisplatin.
