Diverse functionalized representatives of various classes of sugars, such as thio-, anhydro-, and sulfamido-sugars and myo-inositol oxide, were synthesized and assessed for cytotoxicity against human cancer cell lines (A549, LoVo, MCF-7 and HeLa). The inositol oxide (4) was more active against MCF-7 cells (i.e., an estrogen-dependent breast cancer line), whereas all 3 sulfur-containing compounds showed strongest activity against A549 cells (i.e., a lung adenocarcinoma line). We propose to use a concept of functional 'CARB-pharmacophores' when evaluating a potential for the compounds' general antineoplastic activity. Future studies will determine the reasons for cell-type specificity of these compounds. The thio-sugar motif appears to be a promising lead for future developments.

Background: Actinomycetes are a well-known example of a microbiological origin that may generate a wide variety of chemical structures. As excellent cell factories, these sources are able to manufacture medicines, agrochemicals, and enzymes that are crucial.
Results: In this study, about 34 randomly selected Streptomyces isolates were discovered in soil, sediment, sea water, and other environments.

The combined use of tocilizumab (TCZ) and immune checkpoint inhibitors (ICIs) in cancer treatment is gaining attention, but preclinical studies are lacking. Our study aims to investigate the synergistic anti-tumor effect of TCZ combined with ICIs and its role in treating immune-related adverse events (irAEs). The clinical significance of high interleukin-6 (IL-6) expression in tumor patients was analyzed from the Cancer Genome Atlas (TCGA) database.

Introduction: Renal cell carcinoma (RCC) is one of the most common types of urogenital cancer. The introduction of immune-based combinations, including dual immune-checkpoint inhibitors (ICI) or ICI plus tyrosine kinase inhibitors (TKIs), has radically changed the treatment landscape for metastatic RCC, showing varying efficacy across different prognostic groups based on the International Metastatic RCC Database Consortium (IMDC) criteria.
Materials And Methods: This retrospective multicenter study, part of the ARON-1 project, aimed to evaluate the outcomes of favorable-risk metastatic RCC patients treated with immune-based combinations or sunitinib.

Background: Due to its strong immunogenicity and tumor specificity, neoplastic antigen has emerged as an immunotherapy target with wide therapeutic prospect and clinical application value. Anti-programmed death-1 (PD-1) antibodies reinvigorate T cell-mediated antitumor immunity. So, we conducted single-arm trial to assess the safety and efficacy of PD-1 blockade(Camrelizumab)-activated neoantigen specific cellular therapy (aNASCT) on advanced relapsed non-small lung cancer(NSCLC)(ClinicalTrials.

In our previous phase II T1219 trial for advanced biliary tract cancer (ABTC), the combination of nivolumab with modified gemcitabine and S-1 exhibited promising efficacy, while the programmed-death-ligand-1 (PD-L1) expression did not predict chemoimmunotherapy efficacy. Lymphocyte-activation-gene-3 (LAG-3), a negative immune checkpoint, is frequently co-expressed with PD-L1. This study assessed the predictive value of LAG-3 expression in ABTC patients who received chemoimmunotherapy.
