&lt;p class=&quot;rtejustify&quot;&gt;&lt;strong&gt;Background: &lt;/strong&gt;Garcinia cowa Roxb. ex Choisy (G. cowa) is used in traditional medicine, both for improvement of blood circulation and indigestion, also as an antipyretic and expectorant. &lt;strong&gt;Objective:&lt;/strong&gt; This study investigated the vasorelaxant effects and possible mechanisms of action of G. cowa leaf ethanolic extract (GCE) on the rat isolated thoracic aorta. &lt;strong&gt;Methods:&lt;/strong&gt; The study examined the effects of GCE on isolated rat thoracic aorta, including both endothelium-intact and endothelium-denuded aortic rings, using an organ bath system. Specific inhibitors were used to evaluate the mechanism involved in GCE-induced vasorelaxation.&lt;strong&gt; Results:&lt;/strong&gt; GCE (0.01–10 mg/mL) relaxed endothelium-intact aortic rings, that had been precontracted with phenylephrine. Removal of the endothelium or pretreatment of endothelium-intact aortic rings with NꞶ-nitro-L-arginine methyl ester (L-NAME), or 1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one (ODQ), significantly decreased vasorelaxation induced by the GCE. Indomethacin or propranolol had no effect on the GCE-induced relaxation of the endothelium-intact aortic rings. In endothelium-denuded aortic rings, the relaxation effect of GCE was significantly blocked by 4-aminopyridine (4-AP) and tetraethylammonium (TEA) at the maximum dose of GCE, but not by glibenclamide. In Ca&lt;sup&gt;2&lt;/sup&gt;+-free Krebs solution, GCE (5 and 10 mg/mL) significantly inhibited extracellular Ca&lt;sup&gt;2&lt;/sup&gt;+ induced contraction in pre-contracted rings with high KCl levels. &lt;strong&gt;Conclusions:&lt;/strong&gt; These findings suggest that GCE exhibits both an endothelium-dependent, which is mediated by an eNOS/NO/sGC pathway, and an endothelium-independent pathway, which involves KCa and KV channels opening and extracellular Ca&lt;sup&gt;2&lt;/sup&gt;+ influx inhibition. Kaempferol, isovitexin, quercetin, apigenin, luteolin, and amentoflavone might play a role in inducing the vasorelaxant effect of GCE.&lt;/p&gt;

This study undertook to evaluate the anti-proliferative activity on cancer cells and its cytotoxic effect on normal cells. Here we are reporting for the first time the metabolomic profiling of &lt;em&gt;G. cowa&lt;/em&gt; leaf. &lt;strong&gt;Methods: &lt;/strong&gt;Anti-proliferative potential of ethyl acetate and methanol extract of &lt;em&gt;Garcinia cowa&lt;/em&gt; leaf assessed by MTT assay. Metabolomic profiling obtained by GC/ MS analysis. Nuclear morphology visualized by DAPI staining. Caspase activation analysed through spectrophotometric assay.&lt;strong&gt; Results:&lt;/strong&gt; The study reveals, that the methanolic extract is more potential in inducing anti-proliferative activity than ethyl acetate extract. Robust antiproliferative activity of the methanolic extract evidenced in lung cancer cell line, A549 followed by MCF–7, HepG2, MOLT – 4, MDA-MB-468 cells. The anti-proliferative effect was negligible in normal PBMC. Further, a dose-dependent increase of nuclear fragmentation visualized in A549 cells treated with the methanolic extract. Post methanolic extract treatment upregulation of caspase-3 and caspase-9 also evidenced in A549 cells. GC/MS analysis revealed the presence of phytoconstituents of different phytochemical groups comprising of 3.45% diterpenoid, 5.45% triterpenoid, 11.24% steroid, 2.03% phytosterol, etc. in methanol extract, as well as 4.53% diterpenoid, 2.88% triterpenoid, 1.09% steroid, 2.11% phytosterol, etc. in ethyl acetate extract with considerable biological importance. &lt;strong&gt;Conclusion:&lt;/strong&gt; This is the maiden report of the metabolomic profiling of leaf extracts of&lt;em&gt; Garcinia cowa&lt;/em&gt; which possess a good repository of potentially bioactive molecules that holds a great promise as a future therapeutic agent in combating lung cancer.&lt;/p&gt;

An equal volume of Griess reagent (1% sulphanilamide and 0.1% N-(L-naphthyl)-ethylene diamine dihydrochloride, dissolved in 2.5% H3PO4) was mixed with culture supernatant and color development was measured at 550 nm using a micro plate reader. The amount of nitrite in the culture supernatant was calculated from a standard curve (0&amp;ndash;100 &amp;mu;M) of sodium nitrite freshly prepared in deionized water. Percentage of the NO inhibition was calculated by using nitrate level of IFN-&amp;gamma;/LPS-induced group as the control. &lt;strong&gt;Results:&lt;/strong&gt; Isolated compounds, tetraprenyltoluquinone, rubraxanthone and &amp;alpha;-mangostin from stem bark of &lt;em&gt;Garcinia cowa&lt;/em&gt; Roxb were evaluated for their anti-inflammatory activity. Only &amp;alpha;-mangostin exhibited strong anti-inflammatory activity with 83.42 % inhibition of NO and without inducing severe cytotoxicity at 50&lt;em&gt; &amp;mu;&lt;/em&gt;M. Rubraxanthone showed weak inhibition of NO with 23.86 % inhibition of NO while maintained 77.32 % of cell viability. TPTQ also showed the strong inhibition of NO with 80.98 % inhibition but unfortunately this compound also induced severe cytotoxicity with 39.62% viability. &lt;strong&gt;Conclusion:&lt;/strong&gt; &amp;alpha;-Mangostin exhibited strong anti-inflammatory activity without inducing severe cytotoxicity at 50 &lt;em&gt;&amp;mu;&lt;/em&gt;M. Rubraxanthone showed weak inhibition of NO while Tetraprenyltoluquinone also showed the strong inhibition of NO however this compound also induced severe cytotoxicity.&lt;/p&gt;
