DENDRIMER COMPOSITIONS AND METHODS FOR TREATMENT OF SEVERE ACUTE RESPIRATORY DISTRESS SYNDROME
A method for treating or preventing one or more symptoms of severe inflammation in the lung of a subject in need thereof includes administering to the subject a composition comprising dendrimers complexed, covalently conjugated, or intra-molecularly dispersed or encapsulated with one or more therapeutic or prophylactic agents, in an amount effective to treat, alleviate or prevent one or more symptoms of severe inflammation. The compositions and methods are useful for treating disorders characterized by cytokine storm, for example, for treating or preventing acute lung injury (ALI) and/or acute respiratory distress syndrome (ARDS) results in from ventilator use or infection such as with COVID-19, sepsis, and systemic bacterial infections in a subject in need thereof have been established. Preferably, the dendrimers are generation 4, 5, 6, 7, or 8 poly(amidoamine) (PAMAM) dendrimers, and the therapeutic agents are one or more anti-inflammatory and/or anti-oxidant agents such as N-acetyl cysteine.
Antiviral agents
An antiviral agent is provided, having a phosphorodiamidate morpholino oligomer with an antisense sequence to a portion of a genome of a strain of Zika virus (ZIKV). The antiviral agent finds many uses, such as in a pharmaceutical composition, a method of treating ZIKV-mediated disease, a method of preventing ZIKV-mediated disease, a method of reducing or preventing the replication of ZIKV in a host cell, a method of controlling the spread of ZIKV in donated tissue, a treated tissue sample, and in the manufacture of a medicament for the treatment or prevention or ZIKV-mediated disease.
Polypeptide eye absorption enhancer and use thereof
The present disclosure belongs to the field of pharmaceutical preparations and relates to the design of a series of lipophilic derivatives by using wild-type penetrating peptide penetratin. These penetratin derivatives have a strong ability to penetrate the ocular tissues and do not cause ocular tissue toxicity. As ocular absorption enhancers, non-invasive routes could be used to achieve intraocular drug delivery and increase the ocular bioavailability of drugs. These penetratin derivatives and the ophthalmic drug delivery system constructed by them are used for eye drop administration, which could replace the intraocular injection with poor patients compliance, which greatly enhances the convenience and safety of the treatment of intraocular and fundus diseases.
METHODS FOR ELICITING SELECTIVE HUMORAL RESPONSES
Conjugates of synthetic nanocarriers, complexed with syngeneic (self) proteins adducted with haptens or other poorly immunogenic antigens (antigens of low immunogenicity), elicit selective humoral responses or antibodies against the hapten or antigen and not to self-protein. Compositions include these conjugates, which can be used as vaccines. Methods of making and using them are described herein. In a typical embodiment, a conjugate including a hapten or antigen of low immunogenicity associated with a particular disease (e.g., infection, cancer) can be used as a vaccine by eliciting antibodies that specifically neutralize the hapten or antigen. These hapten (and other poorly immunogenic antigen)-carrying nanocarriers selectively target antigen presenting cells resulting in a strong anti-hapten humoral response, and thus find use in vaccines for cancer (e.g., cancers of lung, cervix, breast, brain, liver pancreas, ovaries, skin, etc.), infectious diseases and inflammatory-mediated diseases, as well as for autoimmune disorders.
METHODS FOR TREATING SUBJECTS SUFFERING FROM ACUTE MYELOID LEUKEMIA WITH FLT3 LIGAND-TARGETED MIR-150 NANOPARTICLES
A nanoparticle delivery system designed for sustained delivery of microRNA-150 (miR-150) to FLT3-overexpressing acute myeloid leukemia (AML) cells, the delivery system comprising poly(amidoamine) (PAMAM) dendrimers complexed with miR-150, wherein at least one dendrimer is surface-functionalized with a ligand specific for FLT3 receptor, and methods for treating AML characterized by FLT3-overexpression are provided.
