[Effect of actoprotectors on Ca, Mg-dependent ATPase activity in the sarcoplasmatic reticulum of rabbit muscles]. 1987

E Ia Kaplan, and A V Limantsev, and Iu Sh Moshkovskiĭ, and L L Palkin, and L V Tat'ianenko

The effect of different chemical compounds on Ca, Mg-dependent ATPase (Ca-ATPase) sarcoplasmic reticulum (SR) hydrolytic activity as well as their actoprotecting (AP) activity, the ability to increase organism's resistance under muscle stress and antihypoxanthic (AH) activity to increase the organism's survival under conditions of low pressure has been studied. The compounds with AP-activity have been shown to be strong inhibitors of Ca-ATPase SR hydrolytic activity. No correlation between AP-activity of the compounds and their effect on Ca-ATPase SR has been found. The membranotropic activity of actoprotectors has been shown by electronic paramagnetic resonance method. A suggestion has been made to use Ca-ATPase SR as a tested object during the forecasting actoprotecting activity of new chemical compounds.

D004578 Electron Spin Resonance Spectroscopy A technique applicable to the wide variety of substances which exhibit paramagnetism because of the magnetic moments of unpaired electrons. The spectra are useful for detection and identification, for determination of electron structure, for study of interactions between molecules, and for measurement of nuclear spins and moments. (From McGraw-Hill Encyclopedia of Science and Technology, 7th edition) Electron nuclear double resonance (ENDOR) spectroscopy is a variant of the technique which can give enhanced resolution. Electron spin resonance analysis can now be used in vivo, including imaging applications such as MAGNETIC RESONANCE IMAGING.

D000252 Calcium-Transporting ATPases Cation-transporting proteins that utilize the energy of ATP hydrolysis for the transport of CALCIUM. They differ from CALCIUM CHANNELS which allow calcium to pass through a membrane without the use of energy.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D012519 Sarcoplasmic Reticulum A network of tubules and sacs in the cytoplasm of SKELETAL MUSCLE FIBERS that assist with muscle contraction and relaxation by releasing and storing calcium ions. Reticulum, Sarcoplasmic,Reticulums, Sarcoplasmic,Sarcoplasmic Reticulums
D013329 Structure-Activity Relationship The relationship between the chemical structure of a compound and its biological or pharmacological activity. Compounds are often classed together because they have structural characteristics in common including shape, size, stereochemical arrangement, and distribution of functional groups.

D017301 Ca(2+) Mg(2+)-ATPase An enzyme that catalyzes the hydrolysis of ATP and is activated by millimolar concentrations of either Ca(2+) or Mg(2+). Unlike CA(2+)-TRANSPORTING ATPASE it does not require the second divalent cation for its activity, and is not sensitive to orthovanadate. (Prog Biophys Mol Biol 1988;52(1):1).
