Publication number: 20190233367Abstract: The invention provides compositions of novel high penetration compositions (HPC) or high penetration prodrugs (HPP) of mustards and mustard-related compounds, which are capable of crossing biological barriers with high penetration efficiency. The HPPs are capable of being converted to parent active drugs or drug metabolites after crossing the biological barrier and thus can render treatments for the conditions that the parent drugs or metabolites can. Additionally, the HPPs are capable of reaching areas that parent drugs may not be able to access or to render a sufficient concentration at the target areas and therefore render novel treatments. The HPPs can be administered to a subject through various administration routes, e.g., locally delivered to an action site of a condition with a high concentration or systematically administered to a biological subject and enter the general circulation with a faster rate.Type: ApplicationFiled: December 4, 2018Publication date: August 1, 2019Inventors: Chongxi YU, Lina XU

PRO-DRUGS OF NSAIAS WITH VERY HIGH SKIN AND MEMBRANES PENETRATION RATES AND THEIR NEW MEDICINAL USES
Publication number: 20190152991Abstract: The novel positively charged pro-drugs of NSAIAs in the general formulas (1, 2a, 2b, 2c, or 2d) “Structure 1, 2a, 2b, 2c, or 2d” were designed and synthesized. The compounds of the general formalas (1, 2a, 2b, 2c, or 2d) “Structure 1, 2a, 2b, 2c, or 2d” indicated above can be prepared from metal salts, organic base salts, or immobilized base salts of NSAIAs with suitable halide compounds. The positively charged amino groups in the pro-drugs in this invention largely increase the solubility of the drugs in water and will bond to the negative charge on the phosphate head group of membrane. Thus, the local concentration of the outside of the membrane or skin will be very high and will facilitate the passage of these pm-drugs from a region of high concentration to a region of low concentration. This bonding will disturb the membrane a little bit and may make some room for the lipophilic portion of the pro-drug.Type: ApplicationFiled: January 22, 2019Publication date: May 23, 2019Inventors: Chongxi YU, Lina XU -
