Abstract
Nine- and twelve-membered triaza-macrocycles were appended to one end of homospermidine to make polyamine lassos. These compounds were shown to be potent polyamine transport inhibitors (PTIs) using pancreatic ductal adenocarcinoma L3.6pl cells, which have high polyamine transport activity. The smaller triazacyclononane-based lasso significantly reduced the uptake of a fluorescent polyamine probe and inhibited spermidine uptake and reduced intracellular polyamine levels in difluoromethylornithine (DFMO)-treated L3.6pl cells. Both designs were shown to be effective inhibitors of 3H-spermidine uptake, with the smaller lasso outperforming the larger lasso. When the smaller lasso was challenged to inhibit each of the three radiolabeled native polyamines, it had similar K i values as those of the known PTIs, Trimer44NMe and AMXT1501. Because of these promising properties, these materials may have future anticancer applications in polyamine blocking therapy, an approach that couples a polyamine biosynthesis inhibitor (DFMO) with a PTI to lower intracellular polyamines and suppress cell growth.

Abstract
A series of kojic acid derivatives based on monoamines, diamines, and triamines have been synthesized in good yield and purity. A spermidine (spd) rescue experiment was applied against MCF-7 cells to evaluate the polyamine transporter selectivity, and in vitro antiproliferative effects were determined against Hela and DU-145 cell lines. Overall, 5b showed the best selectivity for the polyamine transporter and antiproliferative effects. Therefore, the in-silico metabolism profile and ADMET properties of the title compounds were calculated by the PreADMET server. Additionally, physicochemical properties of ligands were predicted by using the Molinspiration online property calculation server.

Abstract
Glioblastoma multiform (GBM) is the most common and devastating type of primary brain tumor, being considered the deadliest of human cancers. In this context, extensive efforts have been undertaken to develop new drugs that exhibit both antiproliferation and antimetastasis effects on GBM. 1,4-Naphthoquinone (1,4-NQ) scaffold has been found in compounds able to inhibit important biological targets associated with cancer, which includes DNA topoisomerase, Hsp90 and monoamine oxidase. Among potential antineoplastic 1,4-NQs is the plant-derived lapachol (2-hydroxy-3-prenyl-1,4-naphthoquinone) that was found to be active against the Walker-256 carcinoma and Yoshida sarcoma. In the present study, we examined the effect of polyamine (PA)-conjugated derivatives of lapachol, nor-lapachol and lawsone on the growth and invasion of the human GBM cells. The conjugation with PA (a spermidine analog) resulted in dose-dependent and time-dependent increase of cytotoxicity of the 1,4-NQs. In addition, in-vitro inhibition of GBM cell invasion by lapachol was increased upon PA conjugation. Previous biochemical experiments indicated that these PA-1,4-NQs are capable of inhibiting DNA human topoisomerase II-α (topo2α), a major enzyme involved in maintaining DNA topology. Herein, we applied molecular docking to investigate the binding of PA-1,4-NQs to the ATPase site of topo2α. The most active molecules preferentially bind at the ATP-binding site of topo2α, which is energetically favored by the conjugation with PA. Taken together, these findings suggested that the PA-1,4-NQ conjugates might represent potential molecules in the development of new drugs in chemotherapy for malignant brain tumors.

Abstract
The motuporamines are natural products isolated from the New Guinea sea sponge Xestospongia exigua. Dihydromotuporamine C contains a large macrocycle and an appended polyamine component and was shown to be both antimetastatic and cytotoxic to human L3.6pl pancreatic cancer cells. A series of macrocycle-polyamine conjugates were prepared, and the sequence of the polyamine component was varied to optimize the antimigration properties (as measured in L3.6pl cells) of this molecular class. A one-carbon spacer between the 15-membered carbocycle and the appended polyamine showed improved antimigration properties. A survey of different polyamine sequences containing two, three, or four carbon spacers revealed that the natural polyamine sequence (norspermidine, a 3,3-triamine) was superior in terms of inhibiting the migration of L3.6pl cells in vitro. An investigation of the respective ceramide and sphingomyelin populations in L3.6pl cells revealed that these molecules can modulate both ceramide and sphingomyelin pools in cells and inhibit cell migration.

Abstract
Dihydromotuporamine C and its derivatives were evaluated for their in vitro antimicrobial activities and antibiotic enhancement properties against Gram‐negative bacteria and clinical isolates. The mechanism of action of one of these derivatives, MOTU‐N44, was investigated against Enterobacter aerogenes by using fluorescent dyes to evaluate outer‐membrane depolarization and permeabilization. Its efficiency correlated with inhibition of dye transport, thus suggesting that these molecules inhibit drug transporters by de‐energization of the efflux pump rather than by direct interaction of the molecule with the pump. This suggests that depowering the efflux pump provides another strategy to address antibiotic resistance.

Abstract
The development of polyamine transport inhibitors (PTIs), in combination with the polyamine biosynthesis inhibitor difluoromethylornithine (DFMO), provides a method to target cancers with high polyamine requirements. The DFMO+PTI combination therapy results in sustained intracellular polyamine depletion and cell death. A series of substituted benzene derivatives were evaluated for their ability to inhibit the import of spermidine in DFMO-treated Chinese hamster ovary (CHO) and L3.6pl human pancreatic cancer cells. Several design features were discovered which strongly influenced PTI potency, sensitivity to amine oxidases, and cytotoxicity. These included changes in (a) the number of polyamine chains appended to the ring system, (b) the polyamine sequence, (c) the attachment linkage of the polyamine to the aryl core, and (d) the presence of a terminal N-methyl group. Of the series tested, the optimal design was N(1),N(1'),N(1″)-(benzene-1,3,5-triyltris(methylene))tris(N(4)-(4-(methylamino)butyl)butane-1,4-diamine, 6b, which contained three N-methylhomospermidine motifs. This PTI exhibited decreased sensitivity to amine oxidases and low toxicity as well as high potency (EC50 = 1.4 μM) in inhibiting the uptake of spermidine (1 μM) in DFMO-treated L3.6pl human pancreatic cancer cells.

Abstract
Organosulfur and selenium chemistry has provided fertile ground for the discovery of novel synthetic methodology and for the design of bioactive molecules with potential therapeutic applications. Thus, acetylenic sulfones have been employed in novel strategies for the synthesis of nitrogen heterocycles, including several biologically active alkaloids. The conjugate addition of nitrogen nucleophiles containing ester or chloroalkyl substituents to acetylenic sulfones was followed by base-mediated intramolecular alkylation or acylation to afford variously substituted piperidines, pyrrolizidines, indolizidines, quinolizidines, decahydroquinolines, and 4-quinolones. The products include the dendrobatid alkaloids (–)-pumiliotoxin C, indolizidines (–)-167B, 207A, 209B, and 209D, as well as (–)-(ent)-julifloridine, (–)-lasubine II, myrtine, and two recently discovered alkaloids from the medicinal plant Ruta chalepensis , which had not been previously synthesized. Acetylenic sulfones were also incorporated on solid supports and employed in the types of cyclizations mentioned above, as well as for Diels–Alder reactions and a large variety of 1,3-dipolar cycloadditions. Conjugate additions of tertiary cyclic α-vinyl amines to acetylenic sulfones generated zwitterions that underwent exceptionally facile formal aza-Cope rearrangements to afford ring-expanded macrocyclic amines. An iterative version was developed and used in the synthesis of motuporamine A and B. With respect to organoselenium chemistry, two classes of compounds are described that function as novel mimetics of the selenoenzyme glutathione peroxidase (GPx), which protects cells from oxidative stress caused by the formation of peroxides during aerobic metabolism. They include cyclic seleninates and spirodioxyselenuranes, both of which efficiently catalyze the reduction of peroxides with thiols and are of potential value in the mitigation of oxidative stress. Their aromatic derivatives are generally less effective catalysts, but substituent effects can be used to modulate their activities. The mechanism of their catalytic cycles has been elucidated and Hammett plots indicate that the oxidation of Se(II) to Se(IV) is the rate-determining step for both classes. A methoxy-substituted aromatic spirodioxyselenurane provided the fastest rate for a small-molecule selenium compound that we have observed to date for the reduction of hydrogen peroxide with benzyl thiol.

Abstract
N-Ethylated N-arylmethyl polyamine conjugates were synthesized and evaluated for their ability to target the polyamine transporter (PAT). To understand the effect of N-ethylation upon PAT selectivity, ethyl groups were appended onto a PAT-selective N (1)-anthracenenylmethyl homospermidine derivative, 1b. Bioevaluation in L1210 murine leukemia cells and in two Chinese hamster ovary cell lines (PAT-active CHO and PAT-deficient CHO-MG) revealed a dramatic decrease in PAT targeting ability upon N (1) or N (5) ethylation of the pharmacophore 1b. Experiments using the amine oxidase inhibitor, aminoguanidine (AG, 2 mM), revealed that the N (9)-ethyl and N (9)-methyl analogues were able to retain their PAT selectivity and cytotoxicity properties in the presence or absence of AG. In contrast, the lead compound 1b (containing a terminal NH 2 group) revealed a dramatic reduction in both its PAT-targeting ability and cytotoxicity in the absence of AG. An improved balance between these three properties of PAT-targeting, cytotoxicity and metabolic stability can be attained via N-methylation at the N (9)-position.
