[Effects of Piper longum L. on chills in Japanese young women: time-dependent changes in skin surface temperature and its recovery rate following the exposure to mild cold stress].
RCT investigating the effect of Piper longum on chills in young women. Participants were assigned to low- and high-dose P. longum groups. Piper longum significantly facilitated the recovery of skin surface temperature in participants with chills, but had no effect in those without chills.
Management of giardiasis by a herbal drug 'Pippali Rasayana': a clinical study.
RCT of Pippali Rasayana, an ayurvedic herbal drug, in 50 patients with giardiasis. After 15 days, 23 out of 25 treated patients showed complete disappearance of Giardia lamblia from stools, with significant reduction in symptoms and improvement in clinical and haematological profiles.
Isolation and Identification of Bioactive Fatty Acid Amides From Piper longum Fruits.
The study isolated and identified bioactive fatty acid amides from Piper longum fruits, revealing significant anti-inflammatory activity for compounds (+)-4 and (+)-7, and potent cytotoxic effects against HT-29 cells for compound 10. These findings suggest promising anti-inflammatory and cytotoxic properties of fatty acid amides from P. longum.
Four new piperidine amide alkaloids from Piper longum fruits and their anti-inflammatory activities.
Phytochemical investigation of Piper longum fruits led to the isolation of 20 piperidine amide alkaloids, including 4 new ones. Compounds 2, 3, 16, and 17 showed significant anti-inflammatory activity by inhibiting NO secretion in LPS-stimulated RAW264.7 cells, outperforming hydrocortisone.
Amide alkaloids from the fruits of Piper longum L. and their bioactivities.
The study isolated and characterized eight new and 17 known amide alkaloids from Piper longum fruits. These compounds were tested for NO inhibition, cytotoxic, and anti-diabetic activities in vitro. Some compounds showed moderate NO inhibitory activity, significant cytotoxic effects against HeLa and HT-29 cells, and moderate inhibitory activity against α-glucosidase and PTP1B.
Piper longum ameliorates obesity by regulating gut microbiota and promoting adipose thermogenesis.
The study investigates the anti-obesity effects of ethanol extract of Piper longum (EEPL) by regulating adipose thermogenesis and gut microbiota. EEPL activates the TRPV1/CaMK2β/AMPK pathway to promote WAT browning and BAT activation, improving obesity in mice. It also restores gut microbiota homeostasis and reduces food intake, suggesting potential for obesity treatment.
In-vivo effects of IVT-15 - A traditional knowledge-inspired formulation for the management of rheumatoid arthritis.
The study scientifically validated the efficacy of IVT-15, a combination of Cyperus scariosus, Zingiber officinale, and Piper longum, against rheumatoid arthritis in animal models. IVT-15 demonstrated anti-arthritic efficacy by reducing arthritis scores and inflammation markers, and showed potential analgesic and immunomodulatory properties.
Eight new amide alkaloids from Piper Longum and their anti-inflammatory activities.
The study isolated eight new amide alkaloids from Piper Longum and evaluated their anti-inflammatory activities. Compound 7 inhibited NO release and the expression of PGE and TNF-α inflammatory factors in RAW 264.7 cells, and was predicted to bind iNOS and COX-2 proteins.
Novel Combination of Traditional Ayurvedic Herb Piper longum L. and Modern Stem Cell Therapy for the Reversal of Glucocorticoid-Induced Osteoporosis.
The study investigated the effects of umbilical cord-derived mesenchymal stem cells (UCMSCs) and Piper longum L. on glucocorticoid-induced osteoporosis in mice. The combination of UCMSCs and P. longum L. extract significantly improved bone health parameters, suggesting a synergistic effect in reversing osteoporosis.
Amide and phenylpropanoid glycosides from the fruits of Piper longum L. and their anti-inflammatory activity.
