New small-size peptides possessing antifungal activity.
The synthesis, in vitro evaluation, and conformational study of a new series of small-size peptides acting as antifungal agents are reported. In a first step of our study we performed a conformational analysis using Molecular Mechanics calculations. The electronic study was carried out using Molecular electrostatic potentials (MEPs) obtained from RHF/6-31G calculations. On the basis of the theo...
متن کاملInsect cardioactive peptides. II. Neurohormonal control of heart activity by two cardioacceleratory peptides in the tobacco hawkmoth, Manduca sexta.
The physiological characteristics of two cardioacceleratory peptides (CAPs) were analysed in the tobacco hawkmoth, Manduca sexta, to determine if either CAP functioned as a cardioregulatory neurohormone. In vivo heart recordings from pharate and newly emerged adults revealed a dramatic increase in heart rate associated with wing-spreading behaviour. Bioassay of whole blood taken from wing-sprea...

متن کاملNatriuretic peptides in heart failure.
Heart failure is a major global health problem affecting 23 million people worldwide. As more cardiac patients survive and live longer with this progressive disease, heart failure is a condition for which the prevalence will grow. Based solely on clinical presentation, heart failure can be difficult to diagnose since its presentation is complex, with signs and symptoms that are nonspecific and ...
متن کاملCytotoxic Peptides Are Small Proteins
Kourie, J. I., and A. A. Shorthouse. Properties of cytotoxic peptideformed ion channels. Am J Physiol Cell Physiol 278: C1063–C1087, 2000.—Cytotoxic peptides are relatively small cationic molecules such as those found 1) in venoms, e.g., melittin in bee, scorpion toxins in scorpion, pilosulin 1 in jumper ant, and lycotoxin I and II in wolf spider; 2) in skin secretions (e.g., magainin I and II ...
