Provided herein are extended release polymers. In one aspect, a composition for sustained release of active ingredients comprises a block polymer having formula: PEG-PCL-PLA-PCL-PEG or PGA-PCL-PEG-PCL-PGA. The extended release block polymers modulate drug release rate based on the hydrophobicity of the PTSgel polymer irrespective of the nature of drug. PTSgel polymers are biodegradable, thermosensitive, and compatible with hydrophilic, hydrophobic, and combinations thereof, biologic or chemical active agents.

Antimicrobial peptides, compositions and methods are described that are useful for treating infectious disease, including those caused by drug resistant Gram-negative bacteria (e.g., Pseudomonas and Acinetobacter) and parasite-caused disease such as malaria. The peptides include a modular kinocidin gamma-core connected directly, or through a short spacer, to a kinocidin C-terminal alpha-helix.

Provided herein are amphiphilic polymers compositions for making aqueous formulations. In one aspect, a solution composition for delivery and release of active ingredients comprises a block co-polymer having formula: PEG-PCL-PLA-PCL-PEG or PGA-PCL-PEG-PCL-PGA or PLA-PCL-PEG-PCL-PLA or PCL-PLA-PEG-PLA-PCL or PCL-PGA-PEG-PGA-PCL. The block co-polymers are biodegradable, stable and compatible with hydrophilic, hydrophobic, and combinations thereof, biologic or chemical active agents. In some embodiments, the block co-polymers enable sustained and/or continuous release of various active agents. In certain embodiments, the block co-polymers can be used to make an artificial tear preparation, a lubricant for joints or wound cover or adhesive.
