(E)-3,4,5-Trimethoxycinnamic acid (O-Methylsinapic acid) is a natural compound derived from the roots and rhizomes of Notopterygium incisum.

Sumatriptan succinate (GR 43175), a serotonin1 (5-HT1) receptor agonist, is used in the acute treatment of a migraine headache.

Valproic Acid (2-Propylpentanoic Acid) is an HDAC inhibitor that suppresses HDAC1 activity and induces HDAC2 degradation, exhibiting oral bioavailability. Valproic Acid activates Notch1 signalling and inhibits the proliferation of small cell lung carcinoma cells, making it applicable for research into epilepsy and bipolar disorder.

Valproic acid sodium salt (Sodium Valproate) is the sodium salt form of valproic acid with anti-epileptic activity. Valproic acid sodium salt is converted into its active form, valproate ion, in blood. Although the mechanism of action remains to be elucidated, Valproic acid sodium salt increases concentrations of gamma-aminobutyric acid (GABA) in the brain, probably due to inhibition of the enzymes responsible for the catabolism of GABA. This potentiates the synaptic actions of GABA. Valproic acid sodium salt may also affect potassium channels, thereby creating a direct membrane-stabilizing effect.

Divalproex Sodium (Valproate semisodium) binds to and inhibits gamma-aminobutyric acid (GABA) transaminase and its anticonvulsant activity may be exerted by increasing brain concentration of GABA and by inhibiting enzymes that catabolize GABA or block the reuptake of GABA into glia and nerve endings. It also is an HDAC inhibitor, Comprised of sodium valproate and valproic acid with anticonvulsant and antiepileptic activities. Divalproex may also work by suppressing repetitive neuronal firing through the inhibition of voltage-sensitive sodium channels.

Nadolol is a non-selective beta-adrenergic antagonist with antihypertensive and antiarrhythmic activities. Nadolol competitively blocks beta-1 adrenergic receptors located in the heart and vascular smooth muscle, inhibiting the activities of the catechola

SNC 80 (NIH 10815) is a potent, highly selective and non-peptide δ-opioid receptor agonist, Ki = 1.78 nM, IC50 = 2.73 nM. SNC80 also selectively activates μ-δ heteromer in HEK293 cells with an EC50 of 52.8 nM. SNC80 shows antinociceptive, antihyperalgesic and antidepressant‐like effects. SNC80 has the potential for multiple headache disorders treatment.

Frovatriptan is a highly potent and cerebroselective agonist of the 5-HT1B/1D receptors, demonstrating the greatest receptor potency among clinically used triptan compounds, and it robustly activates serotonergic signaling pathways to modulate cranial vasoconstriction and trigeminal neurotransmission relevant to migraine pathophysiology, while showing demonstrated clinical efficacy and, in certain predefined endpoints, superiority when administered during the headache phase of migraine attacks accompanied by aura, supporting the optimized pharmacodynamic profile for targeted antimigraine therapy and translational neuropharmacology research.

Biperiden Hydrochloride (KL 373 Hydrochloride) is an anticholinergic antiparkinsonian agent that selectively blocks central M1 cholinoreceptors while exerting atropine-like effects on peripheral parasympathetic structures. Biperiden Hydrochloride is approved for the adjunctive treatment of postencephalitic, idiopathic, and arteriosclerotic Parkinson’s disease, demonstrates minimal impairment of novelty preference compared with other anticholinergics in comparative cognitive studies, and is associated with known adverse effects including drowsiness, vertigo, headache, and dizziness.

RI 61 (sumatriptan succinate) is utilized in the therapy of migraine, cluster headaches, new daily persistent headache, and cyclic vomiting syndrome.

Sumatriptan (GR 43175) hydrochloride can be used in the research of migraine headache that is an orally active agonist of 5-HT1 receptor. The Ki values of Sumatriptan hydrochloride against 5-HT1D, 5-HT1B and 5-HT1A receptors are 17 nM, 27 nM and 100 nM, respectively. [1] [2].

Hexylcaine HCl also called cyclaine or osmocaine, is a short-acting local anesthetic. It acts by inhibiting sodium channel conduction. Overdose can lead to headache, tinnitus, numbness and tingling around the mouth and tongue, convulsions, inability to breathe, and decreased heart function.

Cisapride tartrate is chemically related to metoclopramide, but unlike metoclopramide, it does not cross the blood-brain barrier or have antidopaminergic effects. Cisapride is a serotonin-4 (5-HT4) receptor agonist. Cisapride was indicated for the symptomatic treatment of adult patients with nocturnal heartburn due to gastroesophageal reflux disease. The Food and Drug Administration (FDA) in America stopped the marketing of cisapride as of 14th July 2000. They had received at least 341 reports of heart rhythm abnormalities and these led to 80 deaths. Other reported adverse effects are: headache, diarrhea, abdominal pain, nausea, constipation. Cisapride for animals has been found helpful in some cases of megaesophagus and is a common treatment for feline megacolon. Clarithromycin, erythromycin, and troleandomycin markedly inhibit the metabolism of cisapride. Concurrent administration of certain anticholinergic compounds, such as belladonna alkaloids and dicyclomine, would be e......

(Rac)-SNC80, a racemate of SNC80 (NIH 10815), is a potent, highly selective non-peptide δ-opioid receptor agonist, characterized by a K_i of 1.78 nM and an IC_50 of 2.73 nM. Demonstrating antinociceptive, antihyperalgesic, and antidepressant-like effects, SNC80 holds potential for the treatment of multiple headache disorders [1] [2] [3] [4] [5] [6].

Compound 24 (5-HT2 agonist-1 free base) is a potent agonist for 5-HT2A, 5-HT2B, and 5-HT2C receptors, exhibiting IC50 values of 10 nM, 8.3 nM, and 1.6 nM, respectively. It is utilized in research pertaining to depression, alcoholism, tobacco and cocaine addiction, inflammation, cluster headache, PTSD, seizure disorders, and other central nervous system disorders.

Oxyresveratrol 4-O-β-D-glucopyranoside (Compound 3) is a natural product extracted from the root bark of *Morus atropurpurea*, with potential applications in research on diabetes, arthritis, rheumatism, cough, and headache [1].

Epimagnolin A is a lignan obtained from the flower buds of Magnolia fargesii, which is traditionally used in Asian medicine for treating headache and nasal congestion.

(-)-Fargesol is a nartural product from the flowers buds of Magnolia fargesii,the dried flower buds of M. fargesii, has been used as therapy for nasal empyema and headache.
