• FIG. 15 Conversion of Timosaponin B2 to Timosaponin A3 by lamarinase was confirmed by time of flight mass spectrometry (TOF MS). Disappearance of Timosaponin B2 and appearance of Timosaponin A3 results in an increase in cell death from 16% in the presence of inactivated lamarinase and Timosaponin B2 to 53% in the presence of activated lamarinase and Timosaponin B2.

• compositions comprising inter alia an extract of the taxonomic species of plant referred to as Anemarrhena asph ⁇ deloides Bunge. Further embodiments disclosed herein provide selectively apoptotic methods of using the herein-described compositions.
• the selectively apoptotic compositions described herein possess the activity of inducing apoptosis in abnormally dividing cells, such as cancer cells, while not disturbing the normal cellular processes of normal calls. While not desiring to be limited by theory, it is believed that the active ingredients in the disclosed pharmaceutical compositions act through the caspase pathway to induce apoptosis in cells that have otherwise lost their ability to self-regulate through the process of apoptosis.
• Such active ingredients which are extracted from Anemarrhena asphodeloid.es Bunge inhibit the activity of AKT and mTOR kinases in cancer cell, thereby suggesting their activity in inducing or restoring apoptosis in cancerous cells.
• Treatment of breast cancer cells with aqueous extract of Anemarrhena asphodeloides Bunge induces significant cell death in many of the cancer cell lines.
• Normal mammary epithelial cells and fibroblasts are resistant to the cytotoxic effects of the Anemarrhena asphodeloides Bunge extract.
• Breast cancer cells that were sensitive to the Anemarrhena asphodeloides Bunge extract underwent apoptotic cell death (confirmed by DNA fragmentation, caspase activation, cleavage of PARP and Annexin V staining).
• caspase 3 activation of caspases 4 and 9, which are linked to apoptosis induced by endoplasmic reticulum stress, was also induced by the 0.5 mg/mL aqueous extract of Anemarrhena asphodeloides Bunge.
• This solution induced rapid inacti vation of AKT and mTOR kinases in breast cancer, but not in non-transformed cells.
• Expression of several genes that have well-known pro-apoptotic and anti-proliferative characteristics was also induced by the aqueous extract of Anemarrhena asphodeloides Bunge. It is thus an aspect of the invention to take advantage of the selective pro-apoptotic effects of extracts of Anemarrhena asphodeloides Bunge for the treatment of multicellular organisms, such as mammals, and in particular humans.

• Palliation of climacteric symptoms includes reducing the frequency and/or severity of hot flashes, insomnia, incontinence, depression, etc.
• Administration of Extracts of Anemarrhena asphodeloides Bunge will be via a commonly used administrative route so long as one or more of the plant extracts is available to target tissue via that route.
• Some administrative routes that may be mentioned include: oral, nasal, buccal, rectal, vaginal and/or topical (dermal).
• administration may be by orthotopic, intradermal, subcutaneous, intramuscular, intraperitoneal or intravenous injection.
• Such compositions would normally be administered as pharmaceutically acceptable compositions, described supra.
• Plant extracts of Anemarrhena asphodeloides Bunge selectively induce apoptosis in cancerous cells.
• tumor and non-transformed cell lines and cells were treated with a solution comprising 0.5 mg/mL of dried extract of Anemarrhena asphodeloides Bunge.
• the solution containing 0.5 mg/mL of dried extract of Anemarrhena asphodeloides Bunge is also referred to herein as BN108.
• Figure 1 shows the percentage of cells that bound Annexin V after 24 hours of treatment for three breast cancer cell lines, three prostate cancer cell lines, three immortalized mammary cell lines and normal fibroblasts.
• the percent apoptosis rate for BN108-treated breast and prostate cancer cells ranged from 20% to 80%, while the percent apoptosis rate for BN108-treated immortalized mammary cells was negligible and for BN108-treated normal fibroblasts was less than 10%.
• BN108 induces activation of caspase 4 and caspase 9, which are linked to apoptosis induced by endoplasmic reticulum stress, in BT474 cells.
• BT474 cells were treated with BN108 in the presence or absence of a specific caspase-4 inhibitor.
• Activity of caspases -4 and -9 were quantified using fluorometric assays (Biovision, Inc.) Expression levels of both of these apoptosis-linked caspases were increased several fold over their expression levels in the presence of control. The expression levels of both caspase-4 and caspase-9 are reduced below control levels in the presence of BN108 and a caspase-4 inhibitor.
• caspase 4 leads to the inhibition of caspase-9 activity, indicating that caspase-4 activation is apical in the apoptotic process induced by BN108.
• Treatment of breast cancer cells with BN108 inhibits activity of AKT and mTOR kinases.
• Expression array analysis of BN108-induced changes identified several transcripts with roles in growth arrest and/or apoptosis that are upregulated.
• the upregulated genes with roles in growth arrest and/or apoptosis are: p21CIP, stratifin, cyclin G2, GDF15 and Bim.
• Downregulated genes Growth factors, VEGF, amphiregulin, miR 17-92 and C-myc. Changes in expression of corresponding proteins were confirmed by Western blotting.
• BN108 induces expression of REDD1/DDIT4, whose protein product is a negative regulator of mTORCl.
• BN108 induces REDDl, a gene whose expression is associated with apoptosis, and inhibits mTORCl signaling in breast cancer cells.
• Figure 3A shows Western blot analysis of expression of REDD 1 and phosphorylation of mTOR targets s6 kinase and 4eBP in breast cancer cell line BT474. None of these changes were observed in immortalized non-transformed mammary epithelial cell line MCFlOA (not shown).
• Figure 3B shows that BN108 also inhibits activity of AKT in breast cancer but not MCFlOA cells.
• BN108 As shown in Figure 4A, treatment with BN108 inactivates AKT kinase in breast cancers cells BT474, but not in normal mammary epithelial cells MCFlOA.
• SREBP2 is activeated by BN108 in both the cancer cells (BT474) and the non-cancerous cells (MCFlOA).
• BN108-induced cell death is accompanied by caspase activation and DNA fragmentation. BN108 does not induce generation of reactive oxygen species, DNA damage or mitochondrial dysfunction.
• induction by BN108 of stress response gene REDDl could be related to the observed inhibition of activity of mTOR complex, as REDDl is a negative regulator of TORC.
• Example 2 Isolation of Timosaponin A3 and Timosaponin B2 from an extract of Anemarrhena asphodeloides Bunee
• Timosaponin A3 and Timosaponin B2 were separated from an extract of Anemarrhena asphodeloides Bunge as described in general herein above.
• the isolated Timosaponin A3 and Timosaponin B2 were characterized by GC Mass Spec as described herein above.
• Timosaponin A3 and Timosaponin B2 [0106] The effect of Timosaponins A3 and B2 on the viability of breast cancer cells and normal epithelial cells was tested by treating cells with either 0.5 mg/mL BN108, 4 ⁇ g/mL Timosaponin A3, 50 ⁇ g/mL Timosaponin B2, inactivated lamarinase alone or lamarinase- treated Timosaponin B2 (4 ⁇ g/mL) for 24 hr.
• Timosaponin A3 induced cell death in BT474 cells
• Timosaponin B2 'Tsp B2
• lamarinase alone did not induce cell death in BT474 cells
• treatment of 4 ⁇ g/mL Timosaponin B2 with lamarinase resulted in nearly as great an induction in cell death in BT474 cells as was induced by 4 ⁇ g/mL Timosaponin A3.
• Timosaponin A3 The difference in activity between Timosaponin A3 and lamarinase treated Timosaponin B2 is, on a molar basis, probably negligible, given that the quotient of the molecular weights of Timosaponin B2 (920 Da) and Timosaponin A3 (740 Da) is roughly equivalent to the ratio of the % dead cells in the Timosaponin A3 and the lamarinase-treated Timosaponin B2.
• TOF MS time of flight mass spectrometry
• Timosaponin B2 and appearance of Timosaponin A3 results in an increase in cell death from 16% in the presence of inactivated lamarinase and Timosaponin B2 to 53% in the presence of activated lamarinase and Timosaponin B2.
• Both BN108 and Timosaponin A3 induce the pro-apoptotic gene REDDl in prostate cancer cells.
• pro-apoptotic gene REDDl is induced in Dul45 prostate cancer cells by treatment with BN108 (0.5 mg/mL dried extract of Anemarrhena asphodeloides Bunge) and Timosaponin A3 (7.5 ⁇ M).
• 5 Timosaponin A3 (5 ⁇ M) and BN108 (0.5 mg/mL) increase phosphorylation of elF2a, increase expression of SREBP2 and increase expression of IDIl.
