<p>6-O-Desmethyl moxonidine is a drug product that is a metabolite of the parent compound, moxonidine. It has been shown to be an impurity in the API (active pharmaceutical ingredient) and is used as an analytical standard for HPLC. 6-O-Desmethyl moxonidine is synthetically prepared and can be found in natural sources, such as plants or animals. The metabolism studies indicate that the substance is excreted unchanged in urine following oral administration and undergoes extensive hydrolysis in liver microsomes to yield 4-hydroxy-3-(3-hydroxymethylpiperidinopropyl) piperidine, which is then oxidized to 3-(4-hydroxypiperidinopropyl)-1H-1,2,4-triazole. This product may cause skin irritation.</p>

<p>2'-Epi-lamivudine is a chiral, racemic mixture of the two enantiomers of lamivudine. The synthesis and purification of 2'-epi-lamivudine is achieved by using a chiralpak column to separate the optical isomers from each other and then an immunoaffinity column to remove the undesired enantiomer (the S-enantiomer). The final product is a mixture of both enantiomers in a 1:1 ratio, which has been shown to have antiviral activity against HIV.<br>2'-Epi-lamivudine has been shown to be more potent than its parent compound lamivudine and is less toxic. This antiviral agent inhibits HIV replication by inhibiting reverse transcriptase, which is an enzyme that synthesizes viral DNA from viral RNA. It also has anti-inflammatory properties that may be due to inhibition of prostaglandin synthesis.</p>

<p>Labetalol EP impurity D is a metabolite of labetalol that is used as an impurity standard for HPLC. This impurity has been identified in the drug product and also in the drug development process. Labetalol EP impurity D is one of many metabolites that can be formed by cytochrome P450 enzymes.

<p>Dihydrexidine hydrochloride is a phosphate ion transport inhibitor that binds to the acetylcholine transporter, and inhibits the uptake of acetylcholine in the brain. It is used as an opioid analgesic, as well as to treat depression, cognitive disorders, and Parkinson's disease. Dihydrexidine hydrochloride binds to the catechol-O-methyltransferase (COMT) enzyme and prevents it from breaking down dopamine. This leads to increased levels of dopamine in the synapse and enhanced transmission of nerve impulses between neurons. Dihydrexidine hydrochloride also has been shown to bind to antigen molecules on cells, which may be important for its antiviral properties.</p>
