A series of novel compounds carrying 1,2,4-triazole scaffold was synthesized and evaluated for their anticancer activity against a panel of cancer cell lines using MTT assay. Compounds 8a, 8b, 8c, 8d, 10b, 10e, and 10 g showed remarkable antiproliferative activity against the tested cell lines. Compounds 8a, 8b, 8c, 8d, 10b, 10e, and 10 g with the least IC values in MTT assay were tested against three known anticancer targets including EGFR, BRAF and Tubulin. The results revealed that compounds 8c and 8d showed almost same BRAF inhibitory activity and were discovered to be potent inhibitors of cancer cell proliferation and were also observed to be strong Tubulin inhibitors. Moreover, 8c also showed the best EGFR inhibition with IC = 3.6 μM. Finally molecular modeling studies were performed to explore the binding mode of the most active compounds to the target enzymes.

Comparative Analysis of 4NQO- and Ethanol-Induced Oral Epithelial Dysplasia and Oral Squamous Cell Carcinoma in Male and Female Mice: Association With Peripheral Blood Inflammatory Markers.

Background: Considering that peripheral blood biomarkers are prognostic predictors for several human tumors, this study aimed to comparatively analyze the association of hematological alterations with the incidence of epithelial dysplasia (ED) and oral squamous cell carcinoma (OSCC) in male and female mice treated with 4-nitroquinoline-N-oxide (4NQO) and ethanol (EtOH).
Methods: 120 C57Bl/6J mice (60 males and 60 females) were allocated to four groups (n = 15). They were treated firstly either with 5 mg/mL propylene glycol (PPG) or 100 μg/mL 4NQO in the drinking water for 10 weeks, followed by sterilized water (HO) or 8% EtOH (v/v) for 15 weeks, as follows: PPG/HO, PPG/EtOH, 4NQO/HO, and 4NQO/EtOH (CEUA-UFU, #020/21).

Background: Anaplastic thyroid cancer (ATC) is a highly lethal disease, often diagnosed with advanced locoregional and distant metastases, resulting in a median survival of just 3-5 months. This study determines the stratified effectiveness of baseline treatments in all combinations, enabling precise prognoses prediction and establishing benchmarks for advanced therapeutic options.
Methods: The study extracted a cohort of pathologically confirmed ATC patients from the Surveillance, Epidemiology, and End Results program.
Targeting p38γ synergistically enhances sorafenib-induced cytotoxicity in hepatocellular carcinoma.

Sorafenib (Sora) is a first-line treatment for patients with advanced hepatocellular carcinoma (HCC). It can significantly improve the survival rate of patients with advanced HCC, but it is prone to drug resistance during treatment, so the therapeutic effect is extremely limited. Here, we demonstrate that an elevated expression of protein kinase p38γ in hepatocellular carcinoma cells diminishes the tumor cells' sensitivity to Sora.

The paper presents the results of modern research on the effects of electromagnetic terahertz radiation in the frequency range 0.5-100 THz at different levels of power density and exposure time on the viability of normal and cancer cells. As an accompanying tool for monitoring the effect of radiation on biological cells and tissues, spectroscopic research methods in the terahertz frequency range are described, and attention is focused on the possibility of using the spectra of interstitial water as a marker of pathological processes.
