Human muscle tissues involve striated and smooth muscles. Each muscle
tissue possesses its own special function. Differences of physiology
functions among the muscle tissues are mainly determined by their various
initiation and signal transmission systems, defined as the pre-muscle
molecular motor mechanism, or initiating and regulating mechanism. The
current medications, drugs, and therapies for diseases and symptoms
related abnormal increased muscle tone or excessive muscle contraction
are aimed just at the pre-muscle molecular motor mechanisms, whereas
without directly intending to effect on the muscle molecular motor
mechanism i.e. the contractile apparatus mechanism at all, which,
however, is in common for all kinds of muscle tissues. The muscle
molecular motor mechanism mainly involves recycling of actin-myosin
filament cross-bridge formation and sliding movement. In the process,
bio-energy provided by ATP hydrolysis is necessarily required. Therefore,
abnormal increased muscle tone or excessive contraction of muscle tissues
under diseased conditions may be modified by inhibition of the muscle
molecular motor with the actin-myosin ATPase inhibitor, which blocks
hydrolysis of ATP, then reduces release of bio-energy for the muscle
contraction.Our studies in vitro and in vivo have demonstrated that BDM,
an ATPase inhibitor, thereby, its analogues, derivatives, and other
chemicals possessing similar effect on ATPase may be used as bio-energy
muscle relaxants (general muscle relaxants).
