Summary: This study presents the design, synthesis, and evaluation of a series of novel tryptamine derivatives with 5-HT 1B R activation. Several compounds were identified as more potent 5-HT 1B R activators compared to the FDA-approved drug sumatriptan. The molecular docking results provided insights into the binding mode and interactions between the compounds and 5-HT 1B R.

Summary: This study aimed to investigate the prevalence of triptan use among patients with migraine who have contraindications to triptan usage and the specifics of the medication prescribed. The results showed that a considerable proportion of patients with contraindications were still prescribed triptan medication.

Summary: This study investigated the role of downstream neural circuits of serotonergic neurons in regulating feeding in rats. Using optogenetics and other methods, the researchers found that these circuits interact with satiety hormones, revealing the regulatory mechanisms of these hormones.

Summary: Stress-related neuropsychiatric disorders affect nearly everyone worldwide, with females experiencing higher levels of stress and anxiety. The role of serotonin receptor in stress and anxiety is thought to contribute to the sex-based difference between male and female animals. The current preclinical study investigates the role of serotonin 5HT-5A and 5B receptor in stress and anxiety in male and female rodents, revealing a region-specific association between these receptors under stressful conditions.

Summary: Serotonin amplifies platelet functional responses by binding to 5HT(2A)R. However, developing antagonists for 5HT(2A)R as therapeutic agents in cardiovascular diseases has been challenging. In this study, a custom-made 5HT(2A)RAb was found to block platelet function and protect against thrombogenesis without impairing normal hemostasis.

Summary: This post-hoc analysis examined the efficacy of riemegpant in treating migraine in adults based on triptan treatment experience. The results showed that riemegpant was effective in all groups, except for triptan-naive participants.

Summary: This study aims to provide a definition of triptan failure, which can quantitatively assess the efficacy of triptans in clinical practice and help explore new acute migraine treatments.

Summary: The study found that the risk for comorbid cardio- and cerebrovascular diseases is higher in the working-aged migraine population of Finland, especially among women. Self-reported hypertension, high serum cholesterol, and any diabetes were more common among migraineurs compared to controls.

Summary: This study evaluated the geographic variations in triptan and opioid prescribing patterns for patients with migraine. Results showed that opioids were widely used, while triptans were less commonly prescribed. The findings suggest that there is room for improvement in the acute treatment of migraine attacks.

Summary: Over a 25-year period, triptan use in Denmark has increased, but patient adherence remains low, likely due to disappointing efficacy and/or unpleasant side effects. Triptan discontinuation rates are high, indicating poor implementation of clinical guidelines.

Summary: This study aimed to uncover the mechanisms of triptan using metabolomics and transcriptomics in spontaneous migraine attacks. It found three differential metabolites associated with triptan treatment: cortisol, sumatriptan, and glutamine. The change in sumatriptan levels correlated with a change in the expression of GNAI1 and VIPR2 genes, which are known to regulate cAMP levels. Additionally, the study revealed the effect of triptans on fatty acid oxidation, a mechanism previously not associated with triptans but known to be involved in migraine.

Summary: The study revealed that treatment practices for acute migraine in the emergency department are heterogeneous and deviate from established international recommendations, with concerning trends towards underutilization of triptans and overutilization of opioids in many institutions.

Summary: This study investigated the vascular comorbidity in users and nonusers of triptans over the age of 50. The results showed that there was no significant difference in vascular comorbidity between the two groups, suggesting that triptan use does not increase vascular risk in patients with migraine over the age of 50. However, regular evaluation for contraindications and vascular risk factors is still recommended in this age group.

Summary: The study investigated the association between the efficacy of oral frovatriptan and clinical characteristics of migraine attacks, finding that unilateral pain, phonophobia, cranial autonomic symptoms, and premonitory symptoms were associated with treatment response.
