The present invention relates to novel securinine and norsecurine analogs and their applicapility in treating cellular proliferative disorders.

Hydrogel particles are provided that include a crosslinked polymer and a drug conjugated to the crosslinked polymer. The hydrogel particles may include a pH sensitive moiety and a redox sensitive moiety. The hydrogel particles also may be dispersed in a host hydrogel. Kits and methods of drug delivery and treatment also are provided.

The present invention concerns the use of castanospermine or other alpha-glucosidase inhibitors for the treatment or prevention of Zika virus infections. Aspects of the invention include methods for treating or preventing Zika virus infection by administering an alpha-glucosidase inhibitor (e.g., an alpha-glucosidase I inhibitor) to a subject in need thereof; methods for inhibiting a Zika virus infection in a cell in vitro or in vivo; pharmaceutical compositions; packaged dosage formulations; and kits for treating or preventing Zika virus infection.

This invention relates to a galenical gel formulation for nasal administration of neurotransmitters/neuromodulators such as dopamine, serotonin or pregnenolone and progesterone. The special lipophilic or partly lipophilic system of the invention leads to high bioavailability of the active ingredient in plasma and brain caused by sustained serum levels and/or direct or partly direct transport from nose to the brain.

The present disclosure provides a method for killing persister cells with mitomycin C and/or cisplatin, or derivatives thereof. Recalcitrant infections are difficult to treat due to persister cells, a subpopulation of all bacterial populations that is highly tolerant against all traditional antibiotics since the cells are dormant and antibiotics are designed to kill growing cells. Here, we show that MMC and cisplatin eradicate persister cells through a growth-independent mechanism, cross-linking DNA. We find both agents are effective against both planktonic cultures and highly robust biofilm cultures for a broad range of bacterial species, including commensal Escherichia coli K-12 as well as pathogenic species of E. coli, Staphylococcus aureus, and Pseudomonas aeruginosa. In certain approaches cisplatin is superior to MMC.
