    摘要: The novel positively charged pro-drugs of acetaminophen, acetaminosalol, and related compounds in the general formula (1) 'Structure 1' were designed and synthesized. The 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. The results suggest that the pro-drugs diffuses through human skin ∼150 times faster than does acetaminophen, acetaminosalol, and related compounds. It takes 1-2 hours for acetaminophen and acetaminosalol, and related compounds to reach the peak plasma level when they are taken orally, but these prodrugs only took about ∼50 minutes to reach the peak plasma level when they are taken transdermally. In plasma, more than 90% of these pro-drugs can be changed back to the parent drugs in a few minutes. The prodrugs can be used medicinally for treating any NSAIAs-treatable conditions in humans or animals. The prodrugs can be administered not only orally, but also transdermally for any kind of medical treatments and avoid most of the side effects of NSAIAs. Controlled transdermal administration systems of the prodrugs enables acetaminophen, acetaminosalol, and related compounds to reach constantly optimal therapeutic blood levels to increase effectiveness and reduce the side effects of acetaminophen, acetaminosalol, and related compounds. Another great benefit of transdermal administration of these pro-drugs is that administering medication, especially to children, will be much easier.

    摘要: The novel positively charged pro-drugs of peptides and related compounds in the general formula (1) 'Structure 1' were designed and synthesized. The compounds of the general formula (1) 'Structure 1' indicated above can be prepared by standard peptide synthesis protocols. The positively charged amino group of the pro-drug of peptides not only makes the drugs soluble in water, but also bonds to the negative charge on the phosphate head group of membranes and pushes the pro-drug into the cytosol. The lipophilic portion (by modification of the polar groups with lipophilic alkyl groups) of the prodrugs will facilitate the entering of the drugs into the skin membrane. The results suggest that the pro-drugs diffuses through human skin ~100-1000 times faster than do peptides and related compounds. In plasma, more than 40% of these pro-drugs can change back to the parent drugs in a few minutes. The prodrugs can be used medicinally in treating any peptides and related compounds-treatable conditions in humans or animals. The prodrugs can be administered transdermally for any kind of medical treatments and avoid proteolysis by proteolytic enzymes in the GI tract. Controlled transdermal administration systems of the prodrug enables peptides and related compounds to reach constantly optimal therapeutic blood levels to increase effectiveness and reduce the side effects of peptides and related compounds. Another great benefit of transdermal administration of these pro-drugs is that administering medication, especially to children, will be much easier.

    摘要: The novel positively charged pro-drugs of beta-lactam antibiotics in the general 'Structure 4' were designed. The positively charged amino group of the pro-drug not only makes the drugs soluble in water, but also bonds to the negative charge on the phosphate head group of membranes. This bonding will disturb the membrane a little bit and may make some room for the lipophilic portion of the prodrug. When the molecules of membrane move, the membrane may 'crack' a little bit due to the bonding of the prodrug. This will let the prodrug insert into the membrane. At pH 7.4, only about 99% of amino group is protonated. When the amino group is not protonated, the bonding between the amino group of the prodrug and the phosphate head group of membrane will disassociate, and the prodrug will enter the membrane completely. When the amino group of the prodrug flips to the other side of the membrane and thus become protonated, then the prodrug is pulled into the cytosol, a semiliquid concentrated aqueous solution or suspension. The results suggest that the pro-drugs diffuses through human skin, blood-brain, and blood-milk barriers hundreds times faster than do beta-lactam antibiotics. In plasma, more than 90% of these pro-drugs can change back to the parent drugs in a few minutes. The prodrugs can be used medicinally in treating beta-lactam antibiotics-treatable conditions in humans or animals. The prodrugs can be administered transdermally for any kind of medical treatments. Controlled transdermal administration systems of the prodrug enables beta-lactam antibiotics to reach constantly optimal therapeutic blood levels to increase effectiveness and reduce the side effects of beta-lactam antibiotics. Another great benefit of transdermal administration of these pro-drugs is that administering medication, especially to children or animals, will be much easier.

    摘要: The novel positively charged pro-drugs of diclofenac in the general formula (1), with X = O or S, were designed and synthesized. The compounds of the general formula (1) can be prepared from functional derivatives of diclofenac by reaction with suitable alcohols, thiols, or amines. The positively charged amino groups of these pro-drugs not only largely increase the solubility of the drugs in water, but also bond to the negative charge on the phosphate head group of membranes and push the pro-drug into the cytosol. Experimental results suggest that the pro-drug diethylaminoethyl 2[(2,6-dichlorophenyl)amino]benzene acetate.AcOH diffuses through human skin 250 times faster than 2[(2,6-dichlorophenyl)amino]benzene acetic acid (diclofenac) and ethyl 2[(2,6-dichlorophenyl)amino]benzene acetate. 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 diclofenac-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 diclofenac, most notably GI disturbances such as dyspepsia, gastroduodenal bleeding, gastric ulcerations, and gastritis. Controlled transdermal administration systems of the prodrug enables diclofenac to reach constantly optimal therapeutic blood levels to increase effectiveness and reduce the side effects of diclofenac.

    摘要: The novel positively charged pro-drugs of 1H-imidazo[4, 5-c]quinolin-4-amines and related compounds in the general formula (1) 'Structure 1' or formula (2) 'Structure 2' were designed and synthesized. The compounds of the general formula (1) 'Structure 1' or formula (2) 'Structure 2' indicated above can be prepared from 1H-imidazo[4, 5-c]quinolin-4-amines and related compounds, by reaction with suitable acetic anhydride or acetic chloride. The positively charged amino groups of these pro-drugs not only largely increases the solubility of the drugs in water, but also bonds to the negative charge on the phosphate head group of membranes. This bonding will disturb the membrane a little bit and may make some room for the lipophilic portion of the prodrug. When the molecules of membrane move, the membrane may 'crack' a little bit due to the bonding of the prodrug. This will let the prodrug insert into the membrane.

When the amino group of the prodrug flips to the other side of the membrane and thus becomes protonated, then the prodrug is pulled into the cytosol, a semi-liquid concentrated aqueous solution or suspension. The results suggest that the pro-drugs diffuse through human skin -25 times faster than do 1H-imidazo[4, 5-c]quinolin-4-amines and related compounds. In plasma, more than 90% of these pro-drugs can change back to the parent drugs in a few minutes. The prodrugs can be used medicinally in treating any 1H-imidazo[4,5-c]quinolin-4-amines and related compounds-treatable conditions in humans or animals.
