Abstract:
The following study describes the synthesis of new benzanilide derivatives and their pharmacological investigation on smooth muscle preparations of guinea pigs. All compounds were synthesized in good yields and showed a spasmolytic activity without significant effect on vascular smooth muscles and heart muscle preparations. Moreover, further pharmacological investigations as well as in silico studies were performed to elucidate the mechanism of action. Compound 3 showed the most potent spasmolytic activity with an IC(50) of 3.25microM.

Spasmolytic Agents: Chemical Classification
A major class of centrally acting spasmolytics is the α2-agonist, such as tizanidine. These drugs bind to α2-adrenoceptors, inhibiting the release of the excitatory neurotransmitter glutamate. They also promote...

Centrally Acting Muscle Relaxants: Therapeutic Uses
Centrally acting drugs are classified into spasmolytic and antispasmodic drugs. Spasmolytic drugs such as baclofen, diazepam, and tizanidine inhibit spinal motor neurons and decrease muscle tone. Spasmolytic drugs are administered for severe and chronic spasms due to multiple sclerosis, cerebral palsy, stroke, and spinal cord and muscle injuries. However,...
