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. &lt;strong&gt;Methods:&lt;/strong&gt; AGP was isolated from &lt;em&gt;Andrographis paniculata&lt;/em&gt; 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.&lt;strong&gt; Results:&lt;/strong&gt; 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. &lt;strong&gt;Conclusion:&lt;/strong&gt; Our study efficiently demonstrated that the AGP isolated from &lt;em&gt;Andrographis paniculata&lt;/em&gt; induced apoptosis in NALM-6 cells, which could be used in the therapeutic intervention of leukemia in the future.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">210                         </style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Swadesh Sarkar&lt;sup&gt;1,2&lt;/sup&gt;, Priya K Gopal&lt;sup&gt;2&lt;/sup&gt;, Santanu Paul&lt;sup&gt;2* &lt;/sup&gt;&lt;/strong&gt;&lt;/p&gt;

Chemically, it is a diterpenoid triepoxide molecule and its chemical formula is C&lt;sub&gt;20&lt;/sub&gt;H&lt;sub&gt;24&lt;/sub&gt;O&lt;sub&gt;6&lt;/sub&gt;. Its five-membered unsaturated lactone ring (D-ring) is crucial for anti-tumor potential and carbonyl group at C-18 position is essential to exert important influence on the interaction between triptolide and the targeted protein(s). It is bio-synthesized from deoxy-D-xylullose-5-phosphate (DOXP) pathway in the cell. Triptolide can induce apoptosis in a number of breast cancer cells by up-regulating different pro-apoptotic and down-regulating different anti-apoptotic molecules. &lt;em&gt;In vitro&lt;/em&gt; experiments indicate that it can down regulate several cell cycle related genes and induces S-phase cell cycle arrest. Triptolide treatment can also modulate the expression of different cell signaling molecules, e.g. ERK, NF-&amp;kappa;B, FAK, VEGF, &amp;beta;-catenin, AKT etc. &lt;em&gt;In vivo&lt;/em&gt; experiments indicate that triptolide can effectively reduce breast tumor growth in the mouse model. Apart from the single drug treatment, triptolide can effectively be applied in combination therapy. Application of Triptolide with other chemotherapeutic drugs, very efficiently check the proliferation of tumor cells which reduces the effective concentration of the commercially available drugs thus reducing their toxic sideeffects. Although triptolide is very effective against a number of diseases, its higher degree of multi-organ toxicity limits its use of further clinical trial. Therefore, to reduce the toxic effects, a number of strategies have been developed which increase its water solubility and at the same time decrease the toxic effect. In this review article, we have addressed how triptolide participates in the antitumor processes in breast cancer cells.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">6</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">838</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Swadesh Sarkar&lt;sup&gt;1,2&lt;/sup&gt;, Santanu Paul&lt;sup&gt;2* &lt;/sup&gt;&lt;/strong&gt;&lt;/p&gt;
