The results of experimental therapy of antraxis infected mice with cefazoline (kefzol) and ampicillin incapsulated into liposomes are presented. Protective activity of the same free antibiotics combinated with amixine and leukinferone was evaluated also. Treatment with liposomal cefazoline enhanced mice survival upto 60 per cent, and life period upto 1.3 +/- 0.3 days. After liposomal ampicillin administration for 3 times the same indices were 60 per cent and 6.5 +/- 0.9 days, after 2 times administration--80 per cent and 14 +/- 1.8 days when compared to the groups of the animals treated with free antibiotics. It was shown that administration of ampicillin with amixine or with leukinferone provided enhanced mice survival upto 20 per cent, administration of cefazoline with leukinferone--upto 30 per cent.

Triple-negative breast cancers (TNBCs) typically have a greater immune cell infiltrate and are more likely to respond to immune checkpoint inhibition (ICI) than ER+ or HER2+ breast cancers. However, there is a crucial need to optimize combining chemotherapy strategies with ICI to enhance overall survival in TNBC. Therefore, we developed a high-throughput co-culture screening assay to identify compounds that enhance CD8+ T-cell-mediated tumor cell cytotoxicity.

Vascular smooth muscle K channels critically regulate blood flow and blood pressure by modulating vascular tone and therefore represent attractive drug targets for treating several cardiovascular disorders. However, the lack of potent inhibitors that can selectively inhibit Kir6.1/SUR2B (vascular K) over Kir6.

We report the modulation of reactivity of nitrogen dioxide (NO ) in a charged metal-organic framework (MOF) material, MFM-305-CH in which unbound N-centres are methylated and the cationic charge counter-balanced by Cl ions in the pores. Uptake of NO into MFM-305-CH leads to reaction between NO and Cl to give nitrosyl chloride (NOCl) and NO anions. A high dynamic uptake of 6.

Antagonists of the serotonin receptor 2B (5-HT) have shown great promise as therapeutics for the treatment of pulmonary arterial hypertension, valvular heart disease, and related cardiopathies. Herein, we describe a high-throughput screen campaign that led to the identification of highly potent and selective 5-HT antagonists. Furthermore, selected compounds were profiled for their predicted ability to cross the blood-brain barrier.
