Toxins 'R' Us: more pharmacological tools from nature's superstore.

Abstract:

:Conus venoms from marine cone snails continue to provide novel bioactive components. Two new classes of conopeptide specifically block alpha(1)-adrenoceptors (rho-conopeptide) and noradrenaline transporters (chi-conopeptides). Both classes are small peptides with two disulfide bonds. Rho-conopeptide is structurally similar to alpha-conotoxins, which block nicotinic acetylcholine receptors, whereas the chi-conopeptides are unrelated to other conotoxins. Both types of conopeptides are non-competitive blockers. Because these peptides demonstrate greater selectivity than current drugs in clinical use, they could lead to the development of improved therapeutics.

  • GABA and its receptors in the spinal cord.

    abstract::The importance of the inhibitory neurotransmitter, GABA, within higher centres of the mammalian brain is unquestionable. However, its role within the spinal cord is of equal significance. There have been numerous studies over the past two decades that have established GABA as a neurotransmitter at both post- and presy...
