Tubeimoside I(Lobatoside-H) is an extract from Chinese herbal medicine Bolbostemma paniculatum (MAXIM.) FRANQUET (Cucurbitaceae) has been shown as a potent anti-tumor agent for a variety of human cancers.IC50 value:Target: Anticancer natural compoundin vitro: TBMS I inhibited the proliferation of both HepG2 and L-02 cells in a dose- and time-dependent manner, but HepG2 cells appeared more sensitive to the agent. When exposed to TBMS I for 24, 48 and 72 h, IC50 for HepG2 cells versus L-02 cells were 15.5 vs. 23.1, 11.7 vs. 16.2, 9.2 vs. 13.1 (μM, p<0.01), respectively. TBMS I induced cell shrinkage, nuclear condensation and fragmentation, cell cycle arrest at the G2/M phase, mitochondrial membrane disruption, release of cytochrome c from the mitochondria, activation of caspase 3 and 9, and shifting Bax/Bcl-2 ratio from being anti-apoptotic to pro-apoptotic, all indicative of initiation and progression of apoptosis involving mitochondrial dysfunction [1]. TBMS1-induced molecular events were related to mitochondria-induced intrinsic apoptosis and P21-cyclin B1/cdc2 complex-related G2/M cell cycle arrest [2]. TBMS1 combined with CDDP promoted cell apoptosis, decreased proliferation activity and increased cytosolic Ca2+ levels. Bcl-2 protein expression was down-regulated but Bax was up-regulated. Moreover, GST-π mRNA and protein expression were decreased. TBMS1 reduced the resistance of the cells to CDDP-induced cytotoxicity [4]. Treatment with TBMS1 resulted in dose- and time-dependent inhibition of proliferation, led to arrest in phase G2/M of the cell cycle and increased the levels of intracellular Ca2?. Furthermore, TBMS1 up-regulated the levels of the glucose-regulated protein 78/immunoglobuin heavy chain binding protein (GRP78/Bip), C/EBP homologous protein (CHOP), Bax, and cleaved caspase-3 and down-regulated the levels of Bcl-2 [5].in vivo: TBMS1 significantly inhibited the production of the pro-inflammatory cytokines, TNF-α, IL-6 and IL-1β in vitro and in vivo. Pretreatment with TBMS1 markedly attenuated the development of pulmonary edema, histological severities and inflammatory cells infiltration in mice with ALI [3].

Solamargine is a major steroidal alkaloid glycoside extracted from a traditional Chinese medicinal herb, Solanum nigrum L. (SNL); has been shown to inhibit growth and induce apoptosis of various cancer cells. IC50 value:Target: Anticancer natural compoundin vitro: Solamargine reduced HepG2 cell viability in a concentration-dependent manner. At 7.5μM solamargine decreased cell viability by less than 20% in HepG2 cells. At the highest dose, solamargine decreased cell migration and invasion by more than 70% and 72% in HepG2 cells, respectively. Western blotting and gelatin zymography results showed that solamargine reduced expression and function of MMP-2 and MMP-9 proteins [1]. SM increased phosphorylation of p38 mitogen-activated protein kinase (p38 MAPK) in a time-dependent fashion. SM also inhibited phosphorylation and protein expression of signal transducer and activator of transcription 3 (Stat3), a transcription factor, which was abrogated by the SB203580, a specific inhibitor of p38 MAPK. In addition, SM induced protein expression of p21, one of cyclin-dependent kinase inhibitors, and this was not observed in cell overexpression of Stat3 or cells treated with SB203580 [2]. SM significantly inhibited the growth of SMMC-7721 and HepG2 cells and induced cell apoptosis. Cell cycle analysis revealed that SM caused cell cycle arrest at the G2/M phase. Moreover, SM could up-regulate the expression of caspase-3 [3].

Meropenem is a carbapenem antibiotic, which displaying a broad spectrum of antibacterial activity.Target: AntibacterialMeropenem, a new parenteral carbapenem demonstrated increased activity as compared to imipenem against 336 strains of Neisseria gonorrhoeae, 119 strains of Haemophilus influenzae, and 110 strains of H. Ceftriaxone and ciprofloxacin demonstrated activity superior to that of both carbapenems while the activity of ceftazidime was similar to that of meropenem [1]. Meropenem, like imipenem and various experimental penems, may overcome the resistance problems presented by Class I beta-lactamases [2]. MEROPENEM was rapidly penetrated to the pleural effusion and was retained for a more prolonged time in the pleural effusion than in the blood of patients with accumulated pleural effusion, and it suggested the usefulness of MEROPENEM in antibacterial therapy for patients with pleurisy causing accumulation of pleural effusion [3].Clinical indications: Appendicitis; Bacterial infection; Bacterial meningitis; Bacterial pneumonia; Bacterial respiratory tract infection; Bacterial skin infection; Bacterial urinary tract infection; Bacteroides fragilis infection; Bacteroides infection; Bacteroides thetaiotaomicron infection; Complicated skin and skin structure infectionFDA Approved Date: July 1996Toxicity: In mice and rats, large intravenous doses of meropenem (2200-4000 mg/kg) have been associated with ataxia, dyspnea, convulsions, and mortalities.

Pseudoginsenoside-F11 (PF11), a component of Panax quinquefolium (American ginseng), has been demonstrated to antagonize the learning and memory deficits induced by scopolamine, morphine and methamphetamine in mice. IC50 value: Inhibition of diprenorphine binding with an IC50 of 6.1 μM Target:In vitro: Biochemical experiments revealed that PF11 could inhibit diprenorphine (DIP) binding with an IC50 of 6.1 μM and reduced the binding potency of morphine in Chinese hamster ovary (CHO)-μ cells [2].In vivo: One in vivo model of cisplatin-induced acute renal failure was performed. The results showed that pretreatment with Pseudoginsenoside F11 reduced cisplatin-elevated blood urea nitrogen and creatinine levels, as well as ameliorated the histophathological damage [1]. We tested the effects of Pseudoginsenoside F11 on morphine-induced development of behavioral sensitization and alterations in glutamate levels in the medial prefrontal cortex (mPFC) in freely moving mice by using in vivo microdialysis. As the results shown, Pseudoginsenoside F11 antagonized the development of behavioral sensitization and decrease of glutamate in the mPFC induced by morphine [3].

Daucosterol is a natural sterolin. IC50 value:Target:In vitro: In the study of the effects of daucosterol on the survival of cultured cortical neurons after neurons were subjected to oxygen and glucose deprivation and simulated reperfusion (OGD/R)(2), the results showed that post-treatment of daucosterol significantly reduced neuronal loss, as well as apoptotic rate and caspase-3 activity, displaying the neuroprotective activity. We also found that daucosterol increased the expression level of IGF1 protein, diminished the down-regulation of p-AKT(3) and p-GSK-3β(4), thus activating the AKT(5) signal pathway [1]. Cell counting kit-8 (CCK-8) assay showed that daucosterol significantly increased the quantity of viable cells and the effectiveness of daucosterol was similar to that of basic fibroblast growth factor (bFGF) and epidermal growth factor (EGF) [2]. Daucosterol inhibits the proliferation of human breast cancer cell line MCF-7 and gastric cancer cell lines MGC803, BGC823 and AGS in a dose-dependent manner. Furthermore, daucosterol inhibits murine hepatoma H22 cell growth in ICR mice. Daucosterol treatment induces intracellular ROS generation and autophagy, but not apoptotic cell death. Treatment with ROS scavenger GSH (reduced glutathione), NAC (N-acetyl-l-cysteine) or autophagy inhibitor 3-Methyladenine (3-MA) counteracted daucosterol-induced autophagy and growth inhibition in BGC823 and MCF-7 cancer cells [3].In vivo:
