    Abstract: This invention is for an improved process to co-encapsulate hydrophobic drugs and hydrophilic drugs in phospholipid liposomes. Non-toxic supercritical or near-critical fluids with/without polar cosolvents are utilized to solubilize phospholipid materials and hydrophobic drugs, and form uniform liposomes to encapsulate hydrophobic drugs and hydrophilic drugs.DNA topoisomerase I (Top1) is the target of camptothecin, and novel Top1 inhibitors are in development as anticancer agents. Top1 inhibitors damage DNA by trapping covalent complexes between the Top1 catalytic tyrosine and the 3′-end of the broken DNA. Tyrosyl-DNA phosphodiesterase (Tdp1) can repair Top1-DNA covalent complexes by hydrolyzing the tyrosyl-DNA bond. Inhibiting Tdp1 has the potential to enhance the anticancer activity of Top1 inhibitors and to act as antiproliferative agents. It has been recently reported that neomycin inhibits Tdp1 more effectively than the related aminoglycosides paromomycin and lividomycin A. Inhibition of Tdp1 by neomycin is observed both with single- and double-stranded substrates but is slightly stronger with duplex DNA, which is different from aclarubicin, which only inhibits Tdp1 with the double-stranded substrate. Inhibition by neomycin can be overcome with excess Tdp1 and is greatest at low pH. Aminoglycoside antibiotics and the ribosome inhibitors thiostrepton, clindamycin-2-phosphate, and puromycin are the first reported pharmacological Tdp1 inhibitors. The development of Tdp1 inhibitors as anticancer agents can be envisioned as combinations of Tdp1 and Top1 inhibitors. Moreover, Tdp1 inhibitors might also be effective by themselves as anticancer agents. In addition, Tdp1 inhibitors might be valuable as anti-infectious agents.This invention can produce a co-encapsulated combination drug product consisting of a topoisomerase 1 inhibitor such as camptothecins including neat camptothecin and its derivatives irinotecan, topotecan and other derivatives, and a tyrosyl-DNA phosphodiesterase (Tdp1) such as aminoglycoside antibiotics including neomycin and tetracycline, and the ribosome inhibitors thiostrepton, clindamycin-2-phosphate, and puromycin.

    Abstract: The invention relates to a combination of treatments, more particularly a combination treatment for HIV-1 infection. The present invention is directed to the use of bryostatin-1 and their natural and synthetic derivatives for AIDS therapy, in particular to the use of bryostatins in combination with other active drugs such as Histone Deacetylases (HDACs) inhibitors and anti-retrovirals, for the treatment of HIV-1 latency. According to the present invention, we provide a combination therapy for the treatment of HIV-1 latency which employs bryostatin-1 (and analogues) and one of the following HDAC inhibitors; valproic acid, butyrate derivatives, hydroxamic acids and benzamides. While HDACi can be used in continuous dosing protocol, bryostatins can be used following a cyclical dosing protocol. Bryostatins can be formulated in pharmaceutical acceptable carriers including nanoparticles, phospholipids nanosomes and/or biodegradable polymer nanospheres. This combination therapy needs to be used in patients treated with antiretroviral therapy (HIV-1 protease inhibitors, HIV-1 reverse transcriptase inhibitors, HIV-1 integrase inhibitors, CCR5 co-receptor inhibitors and fusion inhibitors).

    Abstract: The invention involves the use of supercritical or near supercritical fluids to inactivate pathogens in biologic materials which may or may not be contaminated by pathogens. The pathogen reduced material is then inserted into empty, sterile containment vessels. The apparatus can be used as a means to achieve terminal sterilization of the biologic materials. The preferred method of use for the apparatus includes operation of a conveyor belt to move and fill bottles, flasks, containers, or vials in an assembly line to create the finished product in an effective and timely fashion.
