Introduction: Prostate cancer is an androgen-dependent malignancy, and the use of androgen deprivation therapies frequently results in treatment resistance, relapse, and the development of aggressive castration-resistant tumors. Patchouli alcohol, a tricyclic sesquiterpene derived from Pogostemon cablin of the Labiatae family, has demonstrated potential in modulating inflammatory responses and tumor progression. This study aimed to investigate the mechanisms through which patchouli alcohol influences inflammatory pathways associated with prostate cancer using bioinformatics and experimental validation.

Pharmacotherapy for depression includes drugs such as monoamine oxidase inhibitors (MAOIs), tricyclic antidepressants (TCAs), selective serotonin reuptake inhibitors (SSRIs), noradrenaline (NA) and serotonin (5-HT) reuptake inhibitors (NaSSAs), and atypical antidepressants; these drugs exert differentially beneficial effects on symptoms of depression after acute and chronic treatment in animal models. Said effects are established through neuroplastic mechanisms involving changes in neurogenesis and synaptogenesis as result of the activation of intracellular signaling pathways associated with neurochemical and behavioral changes. Antidepressants increase the synaptic availability of monoamines (monoaminergic hypothesis) such as 5-HT, NA, and gamma-aminobutyric acid (GABA) by inhibiting their reuptake or degradation and activating intracellular signaling pathways such as the responsive element binding protein (cAMP-CREB) cascade, which regulates the expression of genes related to neuroplasticity and neurogenesis, such as brain-derived neurotrophic factor (BDNF), in various brain structures implicated in depression.

Melanoma is an aggressive skin cancer with a high risk of cancer-related deaths, and inducing apoptosis in melanoma cells is a promising therapeutic strategy. This study investigates the anti-tumor potential of a novel lucknolide derivative LA-UC as a therapeutic candidate for melanoma. Lucknolide A (LA), a tricyclic ketal-lactone metabolite isolated from marine-derived sp.

We investigated the inhibitory effects of 32 antidepressants on [H]N-methylscopolamine ([H]NMS)-specific binding in the mouse cerebral neocortex to determine which antidepressants should be recommended for patients with Alzheimer's disease (AD). Of those tested, nine antidepressants (10 M) exhibited less inhibitory effect on [H]NMS-specific binding (<35%): tianeptine (a tricyclic); trazodone (a serotonin 5-HT blocker); sulpiride (a dopamine D blocker); fluvoxamine (a selective serotonin reuptake inhibitor (RI)); milnacipran, levomilnacipran, venlafaxine, and desvenlafaxine (serotonin and noradrenaline RIs); and bupropion (a noradrenaline and dopamine RI). Therefore, these antidepressants show little anticholinergic effect in the brain and are recommended for use in patients with AD.

Hypoxanthine-tricyclano is a synthetic adenosine analogue, in which adenine and ribose have been replaced by hypoxanthine and a morpholino-derived tricyclic moiety, respectively. We investigated whether hypoxanthine-tricyclano could influence atrial inotropy and/or chronotropy, two important functions regulated by the A1 receptor, the main adenosine receptor type of the supraventricular myocardium. Paced left atria and spontaneously beating right atria, isolated from male, 30-35 weeks old, Wistar rats, were used.
