The present invention relates to compositions and uses of novel high penetration compositions or high penetration prodrugs (HPP), in particular HPPs for non-steroidal anti-inflammatory agents (NSAIAs), which are capable of crossing biological barriers with high penetration efficiency. The HPPs herein 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, due to the ability of penetrating biological barriers, the HPPs herein 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 herein can be administered to a subject through various administration routes. For example, the HPPs can be locally delivered to an action site of a condition with a high concentration due to their ability of penetrating biological barriers and thus obviate the need for a systematic administration. For another example, the HPPs herein can be systematically administer to a biological subject and enter the general circulation with a faster rate.

Pro-drugs of ibuprofen comprising a thiopropionate or propionamide moiety, wherein the amino group is tertiary and protonated. This positively charged amino groups of these pro-drugs not only largely increases the solubility of the drugs, but also bonds to the negative charge on the phosphate head group of membranes and pushes the pro-drug into the cytosol. Diethylaminoethyl 2-(p-isobutylphenyl) propionate.AcOH for example diffuses through human skin 250 times faster than ibuprofen itself and 125 times faster than ethyl 2-(p-isobutylphenyl) propionate. In plasma, more than 90% of these pro-drugs can change back to the drug in a few minutes. The prodrugs can be used medicinally in treating any ibuprofen-treatable conditions in humans or animals and be administered not only orally, but also transdermally for any kind of medical treatments and avoid most of the side effects of ibuprofen, most notably GI disturbances such as dyspepsia, gastroduodenal bleeding, gastric ulcerations, and gastritis. Controlled transdermal administration systems of the prodrug enables the ibuprofen to reach constantly optimal therapeutic blood levels to increase effectiveness and reduce the side effects of ibuprofen.

Palladium‐catalyzed β‐C(sp3)‐Harylation of aliphatic acid derivatives was achieved by means of 2‐dimethylaminoethylamine auxiliary as a directing group. The β‐C(sp3)‐Harylation reactions with aryl and heteroaryl iodides efficiently afforded the corresponding arylated hydrocinnamic acid derivatives. Direct β‐C(sp3)‐H alkynylation, and arene C−H arylation and alkynylation were also realized under the

effect selective transport of distinct molecular payloads through a liquid membrane. The secret to this success lies in the attachment of a receptor-complementary handle. We find that the trimethylammonium ethylene group present in choline is a general handle for the transport of drug and drug-like species. Furthermore, neurotransmitters possessing ionizable amine termini are also transported. Some limitations
