<p>3a,21-Dihydroxy-5a-pregnane-11,20-dione 21-acetate is a short-acting intravenous anaesthetic that is used in surgical procedures. It has been shown to have antinociceptive properties and can be used as a potent analgesic. 3a,21-Dihydroxy-5a-pregnane-11,20-dione 21-acetate binds to the alpha1 adrenergic receptor and blocks the release of noradrenaline from nerve terminals in the brain. This prevents the activation of neurons in the spinal cord that transmit pain signals to the brain. The drug also inhibits the action of gamma aminobutyric acid on neurones and increases levels of cortisol concentration in blood plasma. The mechanism by which 3a,21 -dihydroxy 5a pregnane 11,20 dione 21 acetate produces its anaesthetic effects has not yet been elucidated.</p>

<p>1-(4-Methylphenyl)butane-1,3-dione is a pyrimidine derivative that is not active against bacteria. It is used as a tetrazolo and has been shown to be systemically active in mice. 1-(4-Methylphenyl)butane-1,3-dione has been shown to inhibit the production of DNA and RNA by inhibiting the activity of both bacterial DNA gyrase and protein synthesis. This drug degrades into water and carbon dioxide, which may provide an explanation for its lack of antibacterial properties.</p>

<p>(7S)-7-Amino-1,2,3,10-tetramethoxy-6,7-dihydro-5H-benzo[g]heptalen-9-one is a hydroxylated analog of demecolcine. It has been shown to be an effective antimicrobial agent with proteolytic and hypoglycemic effects in mice. 7SATM is able to inhibit the activity of human macrophages. This drug has also been shown to have diagnostic potential by binding to a monoclonal antibody that recognizes the myeloperoxidase enzyme on the surface of neutrophils.</p>

<p>1,5-Bis(4-allyldimethylammoniumphenyl)pentan-3-one, dibromide is a reversible inhibitor of acetylcholinesterase. It has been shown to inhibit the enzyme activity in vitro and in vivo. 1,5-Bis(4-allyldimethylammoniumphenyl)pentan-3-one, dibromide has been shown to be an effective inhibitor of nicotinic acetylcholine receptors in model organisms such as Xenopus oocytes and Acetylcholine esterase activated rat pheochromocytoma cells. The molecule also inhibits the phosphorylation of pnitrophenyl phosphate by choline kinase. This inhibiting effect on choline kinase leads to a decrease in the concentration of choline available for neurotransmitter synthesis. Monoclonal antibodies against acetylcholinesterase are used to detect this</p>

<p>The 2-hydroxyphenyl-3-phenylpropenal (HPPA) is a fatty acid with a hydroxyl group. It has been shown to have anti-inflammatory properties and inhibit the production of TNF-α in mice. HPPA is synthesized by the oxidation of oleic acid, which can be catalyzed by a number of different enzymes such as lipoxygenases, cyclooxygenases, or cytochrome P450s. The synthesis can also be inhibited by other substances such as dibromides or tnf-α. HPPA also has potent inhibitory activity against transcription polymerase chain reaction and protein synthesis. This inhibition is due to its carbonyl group that reacts with the intramolecular hydrogen on the enzyme's active site. The reaction mechanism for this inhibition is similar to that of propranolol, another drug used for treatment of inflammatory diseases.</p>
