Abstract: The present invention relates to a compound of the general formula I and the pharmaceutically acceptable salts thereof; where the variables are as defined in the claims and the description. The invention also relates to the compounds of formula I for use in the treatment or prophylaxis of muscle wasting conditions, of skeletal or cardial muscle atrophy, of conditions, in particular of myopathies, which are associated with an increased Muscle RING Finger 1 (MuRF1) expression and of other conditions; to the compounds of formula I for use as a medicament; to a pharmaceutical composition comprising at least one compound of formula I and to a method for treating said conditions.

Abstract: For triggering a discharge lamp powered by a d.c. source and having electrodes disposed in the lamp bulb, a power supply circuit is proposed having a triggering device where, after the start of heating of a cathode (which cathode is in the form of a heated cathode), the triggering device switches a triggering pulse to a discharge path of the lamp, which discharge path is formed by the two electrodes, and initiates a triggering phase, such that the triggering pulse at least partly overlaps in time with the heating phase of the cathode. In this way, reliable triggering of deuterium discharge lamps and hydrogen discharge lamps is possible, particularly in the case of a deuterium lamp having a relatively small opening, e.g. on the order of 0.3 mm.
