Investigation of an anticancer activity of combination of interferon-alpha and gemcitabine on pancreatic cancer cells.

Pancreatic ductal adenocarcinoma (PDAC) is still a clinical challenge due to its deteriorated prognosis. Therefore, new combination chemotherapeutic approaches are of research interest. In this work, we attempted to characterize the effects of gemcitabine and interferon-alpha as well as the combination of both on the metabolic, pro-apoptotic, and proliferative activity of MiaPaca and Panc-1 cells.

Synthesis and in vitro cytotoxicity of benzoxazole-based PPARα/γ antagonists in colorectal cancer cell lines.

A series of benzoxazole-based amides and sulfonamides were synthesized and evaluated for their human peroxisome proliferator-activated receptor (PPAR)α and PPARγ activity. All tested compounds showed a dual antagonist profile on both PPAR subtypes; based on transactivation results, seven compounds were selected to test their in vitro antiproliferative activity in a panel of eight cancer cell lines with different expression rates of PPARα and PPARγ. 3f was identified as the most cytotoxic compound, with higher potency in the colorectal cancer cell lines HT-29 and HCT116.

The impact of the 2014 military conflict in the east of Ukraine and the Autonomous Republic of the Crimea among patients receiving opioid agonist therapies.

Background: Opioid agonist therapies (OAT) for people with opioid use disorders (OUD) have been available in Ukraine since 2004. This study assessed the effect of 2014 Russian invasion of Ukraine on OAT re-enrollment and retention in conflict areas.

Methods: We analyzed the Ukraine national registry of OAT patients containing 1868 people with OUD receiving OAT as of January 2014 in conflict areas (Donetsk, Luhansk, and the Autonomous Republic [AR] of the Crimea).

Antiproliferative, proapoptotic, and tumor-suppressing effects of the novel anticancer agent alsevirone in prostate cancer cells and xenografts.

The aim of this study was to explore the mechanisms of action of alsevirone in prostate cancer (PC) in vitro and in vivo: CYP17A1 inhibition, cytotoxic, apoptotic, and antitumor effects in comparison with abiraterone. The CYP17A1-inhibitory activity was investigated in rat testicular microsomes using high-performance liquid chromatography. Testosterone levels were evaluated using enzyme-linked immunoassay.

Pharmacophore hybridization approach to discover novel pyrazoline-based hydantoin analogs with anti-tumor efficacy.

In search for new and safer anti-cancer agents, a structurally guided pharmacophore hybridization strategy of two privileged scaffolds, namely diaryl pyrazolines and imidazolidine-2,4-dione (hydantoin), was adopted resulting in a newfangled series of compounds (H1-H22). Herein, a bio-isosteric replacement of "pyrrolidine-2,5-dione" moiety of our recently reported antitumor hybrid incorporating diaryl pyrazoline and pyrrolidine-2,5-dione scaffolds with "imidazoline-2,4-dione" moiety has been incorporated. Complete biological studies revealed the most potent analog among all i.
