  • Introduction: Muscle relaxants can be classified into the peripheral-and central-acting drug types ( Table 6.1). The drugs of the peripheral type are also called neuromuscular blocking agents. The peripheralacting muscle relaxants are being used for muscle relaxation upon endotracheal intubation and/or general anaesthesia for surgical operation. The central-acting muscle relaxants are used for treatments of painful muscle contracture caused by locomotorial disorders, and for relaxation of muscle stiffness caused by psychotic tension or by neurosis.

  • Over the past two decades the NCRP has carried out several studies and issued two reports on problems associated with a possible nuclear attack on this country. In each of these reports, any questions centering primarily about a nuclear reactor accident were avoided. The Council noted, however, the increasing interest in the potential of protective actions for alleviating some of the effects of the release of radioactive materials that might ensue in the event of a reactor accident.

  • The benzoacronycine derivative, S23906-1, was character-ized recently as a novel potent antitumor agent through alkylation of theN2 positionof guanines inDNA.We show here that its reactivity towards DNA can be modulated by glutathione (GSH). The formation of covalent adducts between GSH and S23906-1 was evidenced by EI-MS, and the use of different GSH derivatives, amino acids and dipeptides revealed that the cysteine thiol group is absolutely required for complex formation because glutathione disul-fide (GSSG) and other S-blocked derivatives failed to react covalently with S23906-1. ...

  • The reality is more complex since the receptor binding profile of clozapine and the newer atypical antipsychotic agents suggests that D2-receptor blockade is not essential for antipsychotic effect. The atypical drugs act on numerous receptors and modulate several interacting transmitter systems. Clozapine is a highly effective antipsychotic. It has little affinity for the D2-receptor compared with classical drugs but binds more avidly to other dopamine subtypes (e.g. D1, D3 and D4). It blocks muscarinic acetylcholine receptors, as do certain classical agents (e.g.

  • Drugs li KT used in Hyperlipoproteinemias port vehicles in the aqueous media of lymph and blood. To this end, small amounts of lipid are coated with a layer of phospholipids, embedded in which are additional proteins—the apolipoproteins (A). According to the amount and the composition of stored lipids, as well as the type of apolipoprotein, one distinguishes 4 transport forms: Lipid-Lowering Agents Triglycerides and cholesterol are essential constituents of the organism.

  • Overdose, including self-poisoning, causes bradycardia, heart block, hypotension and low output cardiac failure that can proceed to cardiogenic shock; death is more likely with agents having membrane stabilising action (see Table 23.1). Bronchoconstriction can be severe, even fatal, in patients subject to any bronchospastic disease; loss of consciousness may occur with lipid-soluble agents that penetrate the central nervous system. Receptor blockade will outlast the persistence of the drug in the plasma. Rational treatment includes: • Atropine (1-2 mg i.v.

  • The increasing awareness of the importance of chirality in the context of biological activity has stimulated a growing demand for efficient methods for industrial synthesis of pure enantiomers including chiral antiinflammatory drugs such as naproxen (Xin et al., 2001) and ibuprofen (Lee et al., 1995; Ducret et al., 1998; Xie et al., 1998; Arroyo et al., 1999; Chen and Tsai, 2000); antihypertensive agents such as angiotensin-converting enzyme (ACE) inhibitors (e.g., captopril, enalapril, ceranopril, zofenapril, and lisinopril); and the calcium channel- blocking drugs such as diltiazem.

  • Inhibition of Protein Synthesis Most of the antibacterial agents that inhibit protein synthesis interact with the bacterial ribosome. The difference between the composition of bacterial and mammalian ribosomes gives these compounds their selectivity. Aminoglycosides Aminoglycosides (gentamicin, kanamycin, tobramycin, streptomycin, neomycin, and amikacin) are a group of structurally related compounds containing three linked hexose sugars. They exert a bactericidal effect by binding irreversibly to the 30S subunit of the bacterial ribosome and blocking initiation of protein synthesis.

  • Epstein–Barr virus (EBV) is a potent mitogenic and anti-apoptotic agent for B lymphocytes and is associated with several different types of human tumour. The abundantly expressed small viral RNA, EBER-1, binds to the growth inhibitory and pro-apoptotic protein kinase R (PKR) and blocks activation of the latter by double-stranded RNA. Recent evidence has suggested that expression of EBER-1 alone in EBV-negative B cells promotes a tumorigenic phe-notype and that this may be related to inhibition of the pro-apoptotic effects of PKR....

  • Textilinin-1 is a Kunitz-type serine protease inhibitor isolated from the venom of the Australian common brown snake,Pseudonaja textilis. This molecule binds to and blocks the activity of a range of serine proteases, including plasmin and trypsin. Textilinin-1’s ability to inhibit plasmin, a protease involved in fibrinolysis, has raised the possibility that it could be used as an alternative to aprotinin (Trasylol) as a systemic antibleeding agent in surgery.

  • Many pharmacologically important agents are assembled on multimodular nonribosomal peptide synthetases (NRPSs) whose modules comprise a set of core domains with all essential catalytic functions necessary for the incorporation and modification of one building block. Very often, d-amino acids are found in such products which, with few exceptions, are generated by the action of NRPS integrated epimerization (E) domains that alter the stereochemistry of the corresponding peptidyl carrier protein (PCP) bound l-intermediate....
