Abstract
Studies investigating whether there is a causative link between the gut microbiota and lifespan have largely been restricted to invertebrates or to mice with a reduced lifespan because of a genetic deficiency. We investigate the effect of early-life antibiotic exposure on otherwise healthy, normal chow-fed, wild-type mice, monitoring these mice for more than 700 days in comparison with untreated control mice. We demonstrate the emergence of two different low-diversity community types, post-antibiotic microbiota (PAM) I and PAM II, following antibiotic exposure. PAM II but not PAM I mice have impaired immunity, increased insulin resistance, and evidence of increased inflammaging in later life as well as a reduced lifespan. Our data suggest that differences in the composition of the gut microbiota following antibiotic exposure differentially affect host health and longevity in later life.

Abstract
1, 6-Bis[4-(4-amino-3-hydroxyphenoxy)phenyl]diamantine (DPD), a new cytostatic and differentiation inducing agent, was found to inhibit the growth of several cancer cell lines in the National Cancer Institute (NCI) Anticancer Drug Screen system. Previously, we demonstrated that DPD inhibited the growth of human colon cancer cell lines both in vitro and in vivo. In this study, we examined the anticancer effects of DPD on two human leukemia cells lines. DPD exerted growth inhibitory activities in vitro against two human leukemia cell lines, the promyeloid line HL-60 and the lymphoblastic line Molt-3. The in vivo effect of tumor growth suppression by DPD was also observed in mouse xenografts. No acute toxicity was observed after an intra-peritoneal challenge of DPD in "severe combined immune-deficiency" (SCID) mice twice a week. The in vitro study showed HL-60 was more sensitive to DPD than Molt-3 through induction of G(0)/G(1) cell-cycle arrest with the appearance of a hypodiploid DNA fraction. The increased superoxide (O(2)(-)), dissipation of the mitochondrial membrane potential, activation of caspase 3, and increase in annexin V binding were evident before apoptosis in DPD-treated cells. The superoxide dismutase 1 (SOD1) mRNA expression was also decreased in DPD-treated HL-60 and Molt-3 cells. Thus, it appeared that inhibition of SOD might be the major cause for the production of cellular superoxide with concomitant decrease of H(2)O(2) in DPD-treated cells. Addition of antioxidant can reduce DPD-induced mitochondrial damage, caspase activation, and annexin V binding in HL-60 cells. The results suggest that the cellular generation of O(2)(-) plays a role in initiating and coordinating DPD-mediated growth arrest and apoptosis of HL-60 cells. Importantly, addition of arsenic trioxide, a compound capable of reactive oxygen species (ROS) generation, significantly enhanced the in vitro activity of DPD. These results suggest that DPD appears to be a potential new modality in human leukemia therapy.

Abstract
A diamantane derivative 1,6-Bis [4-(4-amino-3-hydroxyphenoxy) phenyl] diamantane (DPD) was found to inhibit the growth of several cancer cell lines in the National Cancer Institute (NCI) Anticancer Drug Screen system. In this study, we examined the in vitro and in vivo effects of DPD on human colon cancer cells. DPD exerted growth inhibitory activities in vitro against three human colon cancer cell lines (Colo 205, HT-29, and HCT-15). DPD-treated cells were arrested at G0/G1 as analysed by flow cytometric analysis. The expression of cyclin D was decreased in DPD-treated cells. The differentiation markers of carcinoembryonic antigen and fibronectin were significantly increased in colon cancer cells after treatment with DPD. The epithelium-like brush borders on HT-29 cell surface were also demonstrated at 1 week after withdrawal from DPD treatment. The DPD-induced cell growth inhibition and differentiation were irreversible after removal of DPD. The in vivo effect of tumour growth suppression by DPD was also observed in mouse xenografts. No acute toxicity was observed after an intraperitoneal challenge of DPD in BALB/c-nude mice weekly. These results suggest that DPD appears to be a new potentially less toxic modality of cancer therapy.

Abstract
BACKGROUND We have previously found that N-1-adamantyl maleimide (AMI) inhibited the growth of SC-M1 tumors in vitro and in vivo. The cytotoxicity of AMI on SC-M1 was accompanied by a decrease of adherent cells and the suppressive effect was associated with conformational changes in cell membrane protein. In order to determine the cellular targets of AMI in human gastric cancer SC-M1 cells, we examined AMI-induced changes in the levels of adhesion molecules CD29 (beta 1 integrin) and CD54 (ICAM-1) and GSH. In addition, we also analyzed changes of apoptosis markers such as annexin V binding to membrane and caspase 3 activity in SC-M1 cells after treatment with AMI. MATERIALS AND METHODS Changes in CD29, CD54, annexin V binding and GSH levels were examined using FITC-conjugated antibodies or fluorescence probes and flowcytometry. Caspase 3 activity was assayed with spectrofluorometry. RESULTS We found that the expression of CD29 and CD54 on SC-M1 was decreased and the caspase 3 activity was increased during the early apoptosis induced by AMI. Moreover, it was found that the GSH content of the cell was depleted within 30 minutes and then recovered. CONCLUSION These results suggest that the cell membrane proteins, such as adhesion molecules (CD29, CD54) and intracellular GSH, were the targets of AMI on SC-M1 cells. Since these membrane alterations were prior to apoptosis they may have transduced a death signal to SC-M1 cells.

Abstract
We have previously found that adamantylmaleimide derivatives inhibited the growth of several cancer cell lines in vitro. In this study we examined the effect of adamantylmaleimide derivatives on the in vivo and in vitro growth of human gastric cancer cells. Experimental results showed that N-1-adamantylmaleimide (AMI) and N-1-(3,5-dimethyladamantyl)maleimide (DMAMI) exert modest growth inhibitory activities in vitro against five different cancer cell lines. In contrast, N-1-(3,5-dimethyl-adamantyl)maleamic acid (DMAMA), N-1-adamantylmaleamic acid (AMA) and N-1-adamantylsuccinimide (ASI) were virtually inactive. These results suggest that the double bond of N-substituted maleimide plays a prominent role in their antitumor activities. Further analysis with flow cytometry showed an accumulation of apoptotic SC-M1 cells after treatment with 3-10 microM AMI or 5-20 microM DMAMI for up to 72 h. DNA fragmentation by gel electrophoresis confirmed that AMI- and DMAMI- induced cytotoxicity led to cell apoptosis. In addition, scanning electron microscopy (SEM) showed that treating cells with AMI (> or = 10 microM) for 24 h, significantly changed the morphology of SC-M1 cells, i.e. they had an irregular flat shape and the cell membrane was porous. The AMI-induced morphological changes of the cell membrane may lead to apoptosis of SC-M1 cells. AMI-induced growth inhibition was observed in vivo using SCID mice bearing SC-M1 tumors. The AMI-induced growth inhibition of SC-M1 tumor was dose-dependent.

Abstract
New N-1-adamantylcitraconimide (compound 1) and N-1-diamantylcitraconimide (compound 2) were synthesized by reaction of citraconic anhydride with 1-aminoadamantane, and 1-aminodiamantane, respectively, followed by imidization with acetic anhydride and sodium acetate. Compound 1, N-1-adamantylmaleimide (compound 3) and N-1-diamantylmaleimide (compound 4) exhibited strong growth-inhibitory activity against four cancer cell lines (Colo 205, Hep G2, SK-BR-3 and Molt-4). Moreover, compound 1 showed relatively specific cytotoxicity against the test tumor cell lines. Compound 2 exhibited growth inhibitory activity against Colo 205, and SK-BR-3 cells, similar to 5-fluorouracil. It was noted that compound 2 showed relatively low cytotoxicity against Molt-4 cells, approximately 42 times lower than 5-fluorouracil. The N-substituents of imides with adamantly substituents have a more potent antitumor activity than the imides with diamantyl substituents. The imides with methyl substituents (compounds 1 and 2) showed relatively higher selectivity against the tested cancer cell lines than the imides without methyl substituents (compounds 3 and 4). Compounds 3 and 4 show good in vitro activities against Staphylococcus aureus and Trichophyton mentagrophytes. Compound 1 had weak antimicrobial activity against T. mentagrophytes.
