Muscle Relaxant Activity

On preliminary basis neuropharmacological profile of ethanolic extract of flowers of Lawsonia inermis was carried out. For assessing the activity of flowers on central nervous system locomotor activity using actophotometer, muscle relaxant activity using rotarod apparatus, pentobarbital-induced hypnosis and anticonvulsant activity by maximal electroshock test was performed.  Ethanolic extract of flowers of Lawsonia inermis decreased the motor activity by 48.63 % and showed 49.03% noteworthy muscle relaxation along with 127.73% potentiation of pentobarbital-induced sleeping time and 66.67% decreased the duration of tonic hind leg extension of seizures activity.  The results conclude that the extract of flowers of Lawsonia inermis has significant central nervous system depressant activity. Further investigations are, however, necessary to explore mechanism(s) of action involved in these pharmacological activities.

Argyreia speciosa (Linn.f.) (Family: Convolvulaceae, Synonyms: Argyreia nervosa) is used in the traditional Ayurvedic systems of medicine as well as in local health folklore. It is commonly known as Vidhaara in Hindi and Hawaiian Baby Woodrose and Elephant creeper in English. It is the large climber and seen throughout India up to an altitude of 500 m. A. speciosa possess various pharmacological activity such as anti-aging, gastroprotective, analgesic & anti-inflammatory, aphrodisiac, antiviral, antidiabetic,  anticonvulsion, antioxidant, antidiarrheal, antiulcer, central nervous system depressant, nematocides, nootropic, anticancer and many more. Apart from this numerous phytoconstituents have been isolated from A. speciosa. Its seeds principally contain lysergamides, eragine and isoeragine which responsible for its hallucinogenic properties. The present paper efforts bring to light the available literature on A. speciosa with respect to traditional, ethnobotanical, phytoconstituents and review of different pharmacological activities.

The Central Nervous System

Synthesis of the 4-chlorobenzoylthiourea compound was carried out by acylating thiourea with 4-chlorobenzoyl chloride. The 4-chlorobenzoylthiourea compound  will increase the lipophilic and the electronic properties other than the lead compounds of benzoylthiourea in order to, by expectation, raise the central nervous system depressant as well. The lipophilic would affect the ability of the compounds in penetrating biological membranes, which is highly dependent on the solubility of the drug within lipid/water. Log P is the most common method used in determining the parameter value. This experiment was to mix two dissolvents (octanol and water) which are immissible. The both levels of the compounds were carefully observed by a spectrophotometer UV-Vis. From the test, the result of log P value of the 4-chlorobenzoylthiourea compound was 2.32, while the theoretical log P value of the compounds, by using the π Hansch-Fujita method is 1.62 and the f Rekker-Mannhold method is 2.225. Consequently, the result of the test shows that there is a significant difference between the progress experiment and both theoretical log P methods. Moreover, in the test of the central nervous system depressant through the potentiation test to thiopental using mice indicates that the 4-chlorobenzoylthiourea compound have potentiation effects to thiopental compared to the lead compounds of benzoylthiourea.

Reissert Compounds

The reactions of isoquinoline and phthalazine Reissert compounds with phthalaldehydic acids and their derivatives have been investigated as a means of synthesizing 1-(3-phthalidyl)isoquinolines. Of a variety of conditions tried those involving phase transfer were found, in general, to be the most suitable. The products, which are analogues of the convulsant alkaloid bicuculline, showed weak central nervous system depressant activity.

Lavandulae aetheroleum, the oil, was obtained by vapor condensation from the flower of Lavandula angustifolia Mill. or Lavandula intermedia Loisel (Lamiaceae) plant. Other names of Lavandulae aetheroleum oil are Al birri, common or English lavender. The Lavandula angustifolia Mill. or Lavandula intermedia Loisel plant is spreading in the Mediterranean, southern Europe, Bulgaria, Russia, and USA. The Lavandula angustifolia Mill. or Lavandula intermedia Loisel plant, is an odor shrub with 1-2 m in height. The oil is a clear, colorless, or pale yellow. The gas chromatography studies reported the following percentage of the major chemical constituents in the oil: linalyl acetate (25-46%), linalool (20-45%), terpinen-4-ol (1.2-6.0%), lavendulyl acetate (> 1.0%), 1,8-cineole (1,8-cineol, cineol, cineole, eucalyptol) (< 2.5%), 3-octanone (< 2.5%), camphor (< 1.2%), limonene (< 1.0%), and α-terpineol (< 2.0%). Medicinal applications of the oil include the treatment of restlessness, anxiety, cardiovascular disorders, insomnia, and gastrointestinal disorders, burns, diarrhea, headache, sore throats, and wounds. Pharmacological effects include experimental and clinical pharmacology. Experimental pharmacology includes anesthetic, anticonvulsant, sedative, anti-inflammatory, antimicrobial, antispasmodic, antispasmodic, central nervous system depressant effects. Clinical pharmacology includes anxiolytic, analgesic, and cardiovascular effects. The oil dose by inhalation = 0.06-0.2 ml/ 3 times/day while oil dose internally = 1-4 drops approximately 20-80 mg on a sugar cube per day. In conclusion, Lavandulae aetheroleum oil had an anesthetic, anticonvulsant, sedative, anti-inflammatory, antimicrobial, antispasmodic, antispasmodic, central nervous system depressant, anxiolytic, analgesic, and cardiovascular effects.
