Aryl And Heteroarylacetic Acids

This group of NSAIDs has received the most intensive attention for new clinical candidates. As a group, they show high analgesic potency in addition to their potent anti-inflammatory activity, needed for treating inflammatory diseases. Among the members of this class shown in Figure 24.18, ketorolac, indomethacin, and tolmetin have the highest risk of GI complications because of their higher affinity for the COX-1 isozymes, whereas etodolac has the lowest risk because of its COX-2 selective...

Nystatin

Group, a trans epoxide, and a glycosidically joined my-cosamine. Like the other polyene antibiotics, natamycin is amphoteric. The mechanism action of the smaller polyenes differs from that of amphotericin B and nystatin. The 26-membered-ring polyenes cause both potassium ion leakage and cell lysis at the same concentration, whereas the 38-membered-ring poly-enes cause potassium leakage at low, fungistatic concentrations and cell lysis at high, fungicidal concentrations. The smaller polyenes are...

Medical Pharmacology, 9th ed. St. Louis, C. V. Mosby, 1978. Neurotransmitter is ACh. Adapted from Goth, A. Medical Pharmacology, 9th ed. St. Louis, C. V. Mosby, 1978. Neurotransmitter is ACh. known as the nicotinic effect of ACh. Larger amounts of nicotine, however, bring about a ganglionic block characterized initially by depolarization, followed by a typical competitive antagonism. To conduct nerve impulses, the cell must be able to carry out a polarization and...

O Synthetic Antibacterial Agents

Several organic compounds obtained by chemical synthesis on the basis of model compounds have useful antibacterial activity for the treatment of local, systemic, and or urinary tract infections. Some chemical classes of synthetic antibacterial agents include the sulfonamides, certain nitrohetero-cyclic compounds e.g., nitrofurans, metronidazole , and the quinolones. Some antibacterial agents that fail to achieve adequate concentrations in the plasma or tissues for the treatment of systemic...
