Article Abstract
To seek novel antitumor agents, we designed and synthesized new 1-tryptophan analogs based on tryptophan catabolism. 1-Alkyl-tryptophan analogues including 1-ethyltryptophan (1-ET), 1-propyltryptophan (1-PT), 1-isopropyltryptophan (1-isoPT) and 1-butyltryptophan (1-BT) were synthesized from tryptophan. We examined whether those compounds had the antiproliferative effects on SGC7901 and HeLa cells line by using MTT assay in vitro, respectively. Compared to tryptophan, all targeted compounds efficiently inhibited proliferation of two cancer cell lines at 2 mmol/L for 48 hours. Among these tryptophan analogs, 1-BT showed the most powerful cytotoxicity against SGC7901 and HeLa cells at 1 mmol/L and 2 mmol/L concentration. These data suggest that some specific tryptophan analogs could be developed as potential anti-neoplastic agents.

Aims: The increasing antimicrobial resistance, particularly in Acinetobacter baumannii, complicates the treatment of infections, leading to higher morbidity, mortality, and economic costs. Herein, we aimed to determine the in vitro antimicrobial, synergistic, and antibiofilm activities of colistin (COL), meropenem, and ciprofloxacin antibiotics, and curcumin, punicalagin, geraniol (GER), and linalool (LIN) plant-active ingredients alone and in combination against 31 multidrug-resistant (MDR) A. baumannii clinical isolates.

Background: Cancer of unknown primary (CUP) is a challenging malignancy characterized by metastatic tumors with an unidentified primary site, even after extensive pathological and radiographic evaluation. Recent advancements in gene expression profiling and comprehensive genomic profiling (CGP) using next-generation sequencing (NGS) have enabled the identification of potential tissue origins, thereby facilitating personalized treatment strategies. Although most cases of CUP present as adenocarcinomas or poorly differentiated tumors, the treatment remains largely empirical, with limited success from molecularly tailored therapies.

Epithelial ovarian cancer (EOC) remains a leading cause of gynecologic cancer mortality, with high rates of recurrence and chemoresistance. Advances in understanding the molecular biology of EOC, particularly BRCA mutations and homologous recombination deficiency (HRD), have led to more targeted therapies. This review provides an updated summary of systemic treatments for EOC, with an emphasis on personalized therapy approaches and emerging therapeutic strategies.

Objectives: To study the molecular mechanisms of LDH-loaded si-NEAT1 for regulating paclitaxel resistance and tumor-associated macrophage (TAM) polarization in breast cancer.
Methods: qRT-PCR and Western blotting were used to detect the expression of lncRNA NEAT1, miR-133b, and PD-L1 in breast cancer SKBR3 cells and paclitaxel-resistant SKBR3 cells (SKBR3-PR). The effects of transfection with si-NEAT1 and miR-133b mimics on MRP, MCRP and PD-L1 expressions and cell proliferation, migration and apoptosis were investigated using qRT-PCR, Western blotting, scratch and Transwell assays, and flow cytometry.
