Abstract
A series of novel 1-(2'-hydroxy-3'-aroxypropyl)-3-aryl-1H-pyrazole-5-carbohydrazide derivatives were synthesized, and the effects of the compounds on A549 cell growth were investigated. The results showed that all of the 1-(2'-hydroxy-3'-aroxypropyl)-3-aryl-1H-pyrazole-5-carbohydrazide derivatives 2 could inhibit the growth of A549 cells in dosage- and time-dependent manners. Typically, compound 2a and 2d induced A549 cells to autophagy but did not cause apoptosis and necrosis in the cells, and 2d had the most autophagy inducing effect in H460 cells. More importantly, 2a and 2d did not inhibit the growth of HUVEC cells.

Abstract
A series of novel 1-arylmethyl-3-aryl-1H-pyrazole-5-carbohydrazide derivatives were synthesized, and the effects of all the compounds on A549 cell growth were investigated. The results showed that all the nine compounds had inhibitory effects on the growth of A549 cells and induced the cell apoptosis. The study on structure-activity relationships and prediction of lipophilicities of compounds showed that compounds with logP values in the range of 3.12-4.94 had more inhibitory effects on the growth of A549 cells.

Abstract
Previously, we found that nine kinds of new morpholin-3-one derivatives could inhibit the growth of A549 lung cancer cells in a dose-dependent manner, but how they performed their function remained unknown. In this paper, we studied the effects of the three more effective morpholin-3-one derivatives {4-(4-chlorophenyl)-6-((4-nitrophenoxy) methyl) morpholin-3-one (1); 6-(4-chlorophenoxy)-4-(4-methoxyphenyl) morpholin-3-one (2); and 6-((4-nitrophenoxy) methyl)-4-phenylmorpholin-3-one (3)} on the cell cycle distribution, apoptosis, and the level of P53 and Fas that are two kinds of important proteins in the regulation of A549 cell growth and apoptosis. According to the results of cell viability, we selected 40 microg/ml of morpholin-3-one derivatives as the most appropriate concentration for the following study. The results showed that the morpholin-3-one derivatives partly blocked the cells at G1 phase, induced apoptosis, and elevated the level of P53 and Fas proteins significantly. The effect of the morpholin-3-one derivates was associated with translocation of P53 and clustering of Fas. Our data suggested that the morpholin-3-one derivates might be promising tools for elucidating the molecular mechanism of lung cancer cell apoptosis and they will be very potential candidates for developing anti-cancer drugs.

Abstract
We synthesized a series of novel small molecules, ethyl 1-(2'-hydroxy-3'-aroxypropyl)-3-aryl-1H-pyrazole-5-carboxylate derivatives 3a-3o, by the reaction of ethyl 3-aryl-1H-pyrazole-5-carboxylate with 2-aryloxymethylepoxide in the presence of potassium carbonate at refluxing in acetonitrile in moderate or excellent yields. We investigated the effects of all the compounds on A549 cell growth. The results showed that 15 compounds could suppress A549 lung cancer cell growth. Among them, compound 3i was the most effective small molecule in inhibiting A549 cell growth. Compound 3f might most effectively induce A549 cell differentiation. Compound 3g remarkably induced cellular vacuolation.

Abstract
We synthesized a series of novel small molecules, 2,3-dihydro-3-hydroxymethyl-1,4-benzoxazine derivatives, by tandem reduction-oxirane opening of 2-nitroaroxymethyloxiranes in moderate or excellent yields. We investigated the effects of all of the compounds on HUVEC apoptosis and A549 cell growth. The results showed that 6,8-dichloro-2,3-dihydro-3-hydroxymethyl-1,4-benzoxazine was the most effective small molecule in promoting HUVEC apoptosis and inhibiting A549 cell proliferation, but 6-amino-2,3-dihydro-3-hydroxymethyl-1,4-benzoxazine could remarkably inhibit HUVEC apoptosis and might induce the formation of microvessel.

Abstract
Previously, we found that 3,4-(methylenedioxy)-1-(2',3'-epoxypropyl)-benzene (safrole oxide) induced a typical apoptosis in A549 human lung cancer cells by activating caspase-3, -8, and -9. In this study, we further investigated which upstream pathways were activated by safrole oxide during the apoptosis. Immunofluorescence assay combined with laser scanning confocal microscopy revealed that both Fas and Fas ligand (FasL) were up-regulated by the small molecule. In addition, Fas protein distribution was altered, showing a clustering distribution instead of a homogeneous one. Subsequently, Western blot analysis confirmed the up-regulations of Fas and its membrane-binding form of FasL (m-FasL), as well as P53 protein. Conversely, safrole oxide hardly affected integrin beta4 subunit expression or distribution, which was reflected from the data obtained by immunofluorescence assay combined with laser scanning confocal microscopy. The results suggested that Fas/FasL pathway might be involved in safrole oxide-induced apoptosis of A549 cells, while integrin beta4 might be irrelevant to the apoptosis. Nevertheless, we first found the strong expression of integrin beta4 in A549 cells. The study first suggested that safrole oxide might be used as a small molecular promoter of Fas/FasL pathway to elicit apoptosis in A549 cells, which would lay the foundation for us to insight into the new strategies for lung cancer therapy.

Abstract
To investigate the effects of chloroquine diphosphate (CQ) on lung cancer cell growth, we treated A549 cells, a lung cancer cell line, with the drug at various concentrations (0.25-128 microM) for 24-72 h. The results showed that, at lower concentrations (from 0.25 to 32 microM), CQ inhibited the growth of A549 cells and, at the same time, it induced vacuolation with increased volume of acidic compartments (VAC). On the other hand, at higher concentrations (64-128 microM), CQ induced apoptosis at 24 h, while its effect of inducing vacuolation declined. The lactate dehydrogenase (LDH) assay showed that with the treatment of CQ 32-64 microM for 72 h or 128 microM for 48 h, CQ induced necrosis of A549 cells. To understand the possible mechanism by which CQ acts in A549 cells, we further incubated the cells with this drug at the concentrations of 32 or 128 microM in the presence of D609, a specific inhibitor of phosphatidylcholine-specific phospholipase C (PC-PLC). The results showed that D609 (50 microM) could inhibit the effects of CQ 32 microM on the viability and VAC, but it could not change the effects of CQ 128 microM on the same. Our data suggested that CQ inhibited A549 lung cancer cell growth at lower concentrations by increasing the volume of lysosomes and that PC-PLC might be involved in this process. The data also indicated that, at higher concentrations, CQ induced apoptosis and necrosis, but at this time its ability to increase the volume of lysosome gradually declined, and PC-PLC might not be implicated in the process.

Abstract
Our previous studies indicate that 3, 4-(methylenedioxy)-1-(2', 3'-epoxypropyl)-benzene (safrole oxide), a newly synthesized compound, induces apoptosis in vascular endothelial cells (VECs) and A549 lung cancer cells. To our knowledge, the inhibition of angiogenesis by safrole oxide has not been reported yet. We report here that cultured rat aorta treated with safrole oxide exhibited a significant microvessel reduction as determined by counting the number of microvessels in a phase contrast microscope. There were more microvessels formed in the presence of A549 lung cancer cells in rat aorta model, while a dramatic inhibition of angiogenesis was obtained by adding 220-450 micromol l(-1) of safrole oxide to the growth medium (P<.01). The culture of rat aorta treated with safrole oxide produced only some abortive endothelial cells but not microvessels. Furthermore, safrole oxide induced antiangiogenic effect in the chorioallantoic membranes (CAM) as a dose dependent manner. Eggs treated with 2-11 micromol 100 microl(-1) per egg of the safrole oxide for 48 h exhibited a significant reduction in blood vessel area of the CAM, a process likely mediated by apoptosis as demonstrated by DNA fragmentation. Our results suggest that safrole oxide has antiangiogenic activity and this effect might occur by induction of cellular apoptosis.
