Introduction: Garcinia cowa (Clusiaceae) is popular among integrative medicine in several communities. 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 G. cowa leaf. Methods: Anti-proliferative potential of ethyl acetate and methanol extract of Garcinia cowa leaf assessed by MTT assay. Metabolomic profiling obtained by GC/ MS analysis. Nuclear morphology visualized by DAPI staining. Caspase activation analysed through spectrophotometric assay. Results: 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{\textendash}7, HepG2, MOLT {\textendash} 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. Conclusion: This is the maiden report of the metabolomic profiling of leaf extracts of Garcinia cowa which possess a good repository of potentially bioactive molecules that holds a great promise as a future therapeutic agent in combating lung cancer.

Introduction: Algae comprise a promising source of novel components with potent therapeutic agents. In particular, algae have been considered as a potential source of new bioactive compounds. The antioxidant data of our previous study with six different algal methanolic extract reveals the presence of high antioxidant, total phenol content and total flavonoid content in Spirogyra triplicata. Thus, we further focused on screening the anti-proliferative activity of six different green algae on five different cancer cell lines like MCF7, A549, HEPG2, REH, MOLT4. Methods: To fulfill our aim we performed MTT assay for testing anti-proliferative activity and DAPI staining for observing nuclear morphology. We also looked into the metabolomic profiling of Spirogyra triplicata by GC-MS chemometric study. Results: The result indicates that after 24 hours of treatment with methanolic extract of Spirogyra triplicata A549 was the most sensitive cell line with IC50 value of 24.07 {\textpm} 1.09 μg/ml. Followed by Rhizoclonium fontinale and Hydrodictyon reticulatum with IC50 value of 25.97 {\textpm} 1.94 μg/ml and 32.50 {\textpm} 1.97 μg/ml respectively. The HEPG2 cell line was the second most sensitive cell line against S. triplicata with IC50 value of 30.20 {\textpm} 1.45 μg/ml. The MOLT4 cell line was detected as most resistant cell line against the green algal extract in this study. Though the methanolic extracts of six green algae showed maximum to moderate anti-proliferative activity on different cancer cell line but no significantly affect on normal PBMC was observed. Nuclear fragmentation was observed in a dose dependent fashion by DAPI staining on A549 cells treated with methanolic extract of Spirogyra triplicata. We further looked into the chemo profiling of Spirogyra triplicata by GCMS analysis. The result of GC-MS clearly indicates presence of nineteen major components and twenty-three minor components which have more or less bioactivity and would help in therapeutics in future. Conclusions: In brief this study indicates for the first time that green algae Spirogyra triplicata induces anti-proliferative activity specifically against A549 cell but not in normal PBMC. It can be concluded that Spirogyra triplicata holds a great promise as a good repository of anti cancer compounds which may be used in future drug discovery.

Introduction: Andrographis paniculata is an herb widely cultivated in South and Southeastern Asia. It has been traditionally used to treat infections and other Physiological disorders for several hundreds. We investigated the anti-leukemic potential of Andrographolide (AGP) isolated from the leaves of this plant against an array of cancer cells to investigate its most efficacies in a particular cancer type. Methods: AGP was isolated from Andrographis paniculata leaves by using column chromatography. The structure was further determined by LC-MS, 1H NMR and 13C NMR. AGP was initially tested against four different cancer cell lines, namely NALM-6 (pre B-ALL), K562 (CML), A549 (lung carcinoma) and MCF-7 (breast carcinoma) using MTT assay at different time points and different concentrations. The effect of the isolated biomolecule was also investigated in inducing apoptosis through the study of cell cycle progression using flow cytometry by PI staining and nuclear fragmentation pattern by DAPI staining and fluorescence microscopy. Results: the spectral analysis of the isolated bio-molecule assured that the compound was AGP. MTT assay data indicated that AGP was most potent to induce cytotoxicity in NALM-6 cells. Further investigation revealed that it effectively induced apoptosis by arresting cell cycle progression and increased the nuclear break down in NALM- 6 leukemic cells. Conclusion: Our study efficiently demonstrated that the AGP isolated from Andrographis paniculata induced apoptosis in NALM-6 cells, which could be used in the therapeutic intervention of leukemia in the future.
