Abstract
In this study, we report a series of newly synthesised sulphonamides of aziridine-2-carboxylic acid (Az-COOH) ester and amide analogues as potent protein disulphide isomerase (PDI, EC 5.3.4.1) inhibitors. The inhibitory activity on PDI was determined against recombinant human PDIA1 and PDIA3 proteins using an insulin reduction assay. These compounds in low micromolar to low nanomolar concentrations showed the effective in vitro inhibitory properties of PDIA1 with weaker effects on PDIA3. Complexes of 15N- and 15N,13C- uniformly labelled recombinant human PDIA1a with two PDIA1 inhibitors were produced and investigated by a protein nuclear magnetic resonance (NMR) spectroscopy. It was found that both C53 and C56 of the PDIA1 enzyme were involved in covalent binding. Finally, in a range of pharmacological studies, we demonstrated that investigated compounds displayed anti-cancer and anti-thrombotic activity. These findings demonstrate that sulphonamides of Az-COOH derivatives are promising candidates for the development of novel anti-cancer and anti-thrombotic agents.

Abstract
A set of styrylpyridinium (SP) compounds was synthesised in order to study their spectroscopic and cell labelling properties. The compounds comprised different electron donating parts (julolidine, p-dimethylaminophenyl, p-methoxyphenyl, 3,4,5-trimethoxyphenyl), conjugated linkers (vinyl, divinyl), and an electron-withdrawing N-alkylpyridinium part. Geminal or bis-compounds incorporating two styrylpyridinium (bis-SP) moieties at the 1,3-trimethylene unit were synthesised. Compounds comprising a divinyl linker and powerful electron-donating julolidine donor parts possessed intensive fluorescence in the near-infrared region (maximum at ~760 nm). The compounds had rather high cytotoxicity towards the cancerous cell lines HT-1080 and MH-22A; at the same time, basal cytotoxicity towards the NIH3T3 fibroblast cell line ranged from toxic to harmful. SP compound 6e had IC50 values of 1.0 ± 0.03 µg/mL to the cell line HT-1080 and 0.4 µg/mL to MH-22A; however, the basal toxicity LD50 was 477 mg/kg (harmful). The compounds showed large Stokes' shifts, including 195 nm for 6a,b, 240 nm for 6e, and 325 and 352 nm for 6d and 6c, respectively. The highest photoluminescence quantum yield (PLQY) values were observed for 6a,b, which were 15.1 and 12.2%, respectively. The PLQY values for the SP derivatives 6d,e (those with a julolidinyl moiety) were 0.5 and 0.7%, respectively. Cell staining with compound 6e revealed a strong fluorescent signal localised in the cell cytoplasm, whereas the cell nuclei were not stained. SP compound 6e possessed self-assembling properties and formed liposomes with an average diameter of 118 nm. The obtained novel data on near-infrared fluorescent probes could be useful for the development of biocompatible dyes for biomedical applications.

Abstract
Three groups of synthetic lipids are chosen for studies: (1) 1,4-dihydropyridines (1,4-DHPs) containing two cationic moieties and their analogues; (2) 3,4-dihydro-2(1H)-pyridones containing a cationic moiety; and (3) acyclic, open-chain analogues, i.e., 2-amino-3-alkoxycarbonylalkylammonium derivatives. 1,4-DHPs possessing dodecyl alkyl chains in the ester groups in positions 3 and 5 and cationic nitrogen-containing groups in positions 2 and 6 have high cytotoxicity in cancer cells HT-1080 (human lung fibrosarcoma) and MH-22A (mouse hepatoma), but low cytotoxicity in the noncancerous NIH3T3 cells (mouse embryonic fibroblast). On the contrary, similar compounds having short (methyl, ethyl, or propoxyethyl) chains in the ester groups in positions 3 and 5 lack cytotoxicity in the cancer cells HT-1080 and MH-22A even at high doses. Inclusion of fluorine atoms in the alkyl chains in positions 3 and 5 of the DHP cycle decreases the cytotoxicity of the mentioned compounds. Structurally related dihydropyridones with a polar head group are substantially more toxic to normal and cancerous cells than the DHP analogues. Open-chain analogues of DHP lipids comprise the same conjugated aminovinylcarbonyl moiety and possess anticancer activity, but they also have high basal cytotoxicity. Electrochemical oxidation data demonstrate that oxidation potentials of selected compounds are in the range of 1.6-1.7 V for cationic 1,4-DHP, 2.0-2.4 V for cationic 3,4-dihydropyridones, and 1.2-1.5 V for 2-amino-3-alkoxycarbonylalkylammonium derivatives. Furthermore, the tested cationic 1,4-DHP amphiphiles possess antiradical activity. Molecular topological polar surface area values for the tested compounds were defined in accordance with the main fragments of compound structures. The determined logP values were highest for dodecyl ester groups in positions 3 and 5 of the 1,4-DHP and lowest for short alkyl chain-containing amphiphiles.

Abstract
The development of targeted drugs for the treatment of cancer remains an unmet medical need. This study was designed to investigate the mechanism underlying breast cancer cell growth suppression caused by fused isoselenazolium salts. The ability to suppress the proliferation of malignant and normal cells in vitro as well as the effect on NAD homeostasis (NAD+, NADH, and NMN levels), NAMPT inhibition and mitochondrial functionality were studied. The interactions of positively charged isoselenazolium salts with the negatively charged mitochondrial membrane model were assessed. Depending on the molecular structure, fused isoselenazolium salts display nanomolar to high micromolar cytotoxicities against MCF-7 and 4T1 breast tumor cell lines. The studied compounds altered NMN, NAD+, and NADH levels and the NAD+/NADH ratio. Mitochondrial functionality experiments showed that fused isoselenazolium salts inhibit pyruvate-dependent respiration but do not directly affect complex I of the electron transfer system. Moreover, the tested compounds induce an immediate dramatic increase in the production of reactive oxygen species. In addition, the isoselenazolothiazolium derivative selectively binds to cardiolipin in a liposomal model. Isoselenazolium salts may be a promising platform for the development of potent drug candidates for anticancer therapy that impact mitochondrial pyruvate-dependent metabolism in breast cancer cells.

Abstract
Aims and Objectives: The aim of the research is to obtain and to investigate the cytotoxicity of a
novel class of non-toxic oximes – derivatives of N-(benzo[4,5]imidazo[2,1-b]thiazol-3-ylmethoxy)-ω-
(hetarylsulfanyl)-alkanamidines.
Materials and Methods:
To assess the possible toxicity of the compounds, acute oral LD50 was calculated.
The calculations were based on tested compounds IC50 values in relation to 3T3 (mouse fibroblast cell line)
using NRU assay. Monolayer tumor cell lines HT-1080 (human fibrosarcoma, ATCC® CCL-121™), MH-22A
(mouse hepatoma, ECACC code, 96121721) and NIH/3T3 (mouse Swiss Albino embryo fibroblasts, ATCC®
CRL-1658™), were cultured in standard medium (Dulbecco`s modified Eagle`s medium) supplemented with
10% fetal bovine serum (“Sigma”).
Results:
E-Stereoselective synthesis of novel N-(benzo[4,5]imidazo[2,1-b]thiazol-3-ylmethoxy)-ω-
(hetarylsulfanyl)alkanamidines as potential cytotoxic agents was carried out in three steps from corresponding
thiones. N-(Benzo[4,5]imidazo[2,1-b]thiazol-3-ylmethoxy)-5-(benzothiazol-2-ylsulfanyl)-pentanamidine exhibits
high activity in vitro on the monolayer tumour cell lines: MG-22A (mouse hepatoma) and HT-1080
(human fibrosarcoma). Besides this, the above compound exhibits low toxicity on the 3T3 cell line and low
estimated acute oral LD50 (LD50 2759 mg/kg).
Conclusion:
In conclusion, such dramatic decreasing of expected acute toxicity and high cytotoxicity by the
introduction of benzo[4,5]imidazo[2,1-b]thiazolyl fragment into N-hydroxy-ω-(hetarylsulfanyl)alkanamidines
were demonstrated for the first time (see, for example, toxicity and cytotoxicity of compound 8b and corresponding
unsubstituted oxime).

Abstract
AIM This study was designed to investigate the mechanism underlying cancer cell apoptosis caused by selenophenoquinolinones and coumarins. MATERIALS AND METHODS Twelve derivatives were studied according to their ability to suppress the proliferation of cancer cells in vitro (i.e., HepG2, MH-22A, MCF-7), induce cell apoptosis, modulate cellular antioxidant enzyme system activities (i.e., SOD, GPx, TrxR), influence the level of ROS, and modulate caspase activity. RESULTS A plausible mechanism of apoptosis is presented. The lack of change in the activity of caspase-8 demonstrates that these compounds affect the intrinsic rather than the extrinsic pathway; moreover, the absence of caspase-9 activation suggests that the studied compounds are involved in the intrinsic pathway of apoptosis in a non-canonical manner. Provisionally, the increase in Smac/Diablo released from the mitochondria removes the inhibitory effect and activates caspase-7, leading to apoptosis. Additionally, the activation of caspase-1 activates effector caspase-7, thereby increasing the amount of cytochrome c and Smac/Diablo released from the mitochondria and ultimately leading to apoptosis. CONCLUSION This present study provides scientific evidence that selenopheno quinolinones and coumarins promote cancer cell apoptosis by ROS depletion and caspase-7 activation in malignant cells.

Abstract
The cyclization of arylalkynes under selenobromination conditions, combined with an acid-induced 3,2-aryl shift, was elaborated as a general synthetic pathway for the preparation of polyhydroxy-2- and -3-arylbenzo[b]selenophenes from the same starting materials. The redox properties, free-radical-scavenging ability, and cytotoxicity against malignant cell lines (MCF-7, MDA-MB-231, HepG2, and 4T1) of the synthesized compounds were explored, and the obtained results were used to consider the structure-activity relationships (SARs) in these compounds. Consequently, the structural features that were responsible for the highly potent peroxyl-radical-scavenging activity were established.

Abstract
Polysubstituted pyridines 4 bearing methoxyphenyl groups at different positions of the ring have been prepared by the alkylation of 6-thioxo-1,6-dihydropyridines 1 or by the oxidation of 1,4-dihydropyridine 6 with manganese triacetate. The multidrug resistance–modulating (P-glycoprotein inhibition) activity of pyridine derivatives 4 comparable with that of verapamil has been revealed.

Abstract
Addition of DMPC considerably inhibits the degradation of Carmofur in neutral phosphate buffer solutions and this drug becomes less influenced by pH. Carmofur stabilization at neutral pH caused by DMPC addition for in vitro studies was characterized and monitored by 1H NMR. Antiproliferative activity studies on various tumor cell lines showed considerable increase of Carmofur ability to prevent tumor cell growth, when it is added as a mixture with DMPC. This technique opens a way for Carmofur drug delivery in neutral and basic media.

Abstract
Synthetic protocols for the preparation of selenium analogues of raloxifene were elaborated. General aim of the current research is to improve the positive impact of selenium atom introduction in drug design. Antiproliferative activity on CCL-8 (mouse sarcoma), MDA-MB-435s (human melanoma), MES-SA (human uterus sarcoma), MCF-7 (human breast adenocarcinoma), HT-1080 (human fibrosarcoma), MG-22A (mouse hepatoma) tumor cell lines, and normal cell line NIH 3T3 (mouse fibroblasts) was studied. Influence of aminoethoxy "tail" and benzoyl group position on SAR was discussed. Results of in vivo studies on BALB/c female mice with 4T1 cell induced breast cancer model showed that selenium analogue of raloxifene is able to suppress estrogen-depending tumor growth.

Abstract
BACKGROUND AND PURPOSE Here, we describe the in vitro and in vivo effects of (4R,5S)-2-(5-methyl-2-oxo-4-phenyl-pyrrolidin-1-yl)-acetamide (E1R), a novel positive allosteric modulator of sigma-1 receptors. EXPERIMENTAL APPROACH E1R was tested for sigma receptor binding activity in a [³H](+)-pentazocine assay, in bradykinin (BK)-induced intracellular Ca²⁺ concentration ([Ca²⁺](i)) assays and in an electrically stimulated rat vas deferens model. E1R's effects on cognitive function were tested using passive avoidance (PA) and Y-maze tests in mice. A selective sigma-1 receptor antagonist (NE-100), was used to study the involvement of the sigma-1 receptor in the effects of E1R. The open-field test was used to detect the effects of E1R on locomotion. KEY RESULTS Pretreatment with E1R enhanced the selective sigma-1 receptor agonist PRE-084's stimulating effect during a model study employing electrically stimulated rat vasa deferentia and an assay measuring the BK-induced [Ca²⁺](i) increase. Pretreatment with E1R facilitated PA retention in a dose-related manner. Furthermore, E1R alleviated the scopolamine-induced cognitive impairment during the PA and Y-maze tests in mice. The in vivo and in vitro effects of E1R were blocked by treatment with the selective sigma-1 receptor antagonist NE-100. E1R did not affect locomotor activity. CONCLUSION AND IMPLICATIONS E1R is a novel 4,5-disubstituted derivative of piracetam that enhances cognition and demonstrates efficacy against scopolamine-induced cholinergic dysfunction in mice. These effects are attributed to its positive modulatory action on the sigma-1 receptor and this activity may be relevant when developing new drugs for treating cognitive symptoms related to neurodegenerative diseases.

Abstract
Organoammonium hydroselenites were synthesized and investigated as potential selective, anticancer prodrugs. These compounds were studied in vitro on human fibrosarcoma (HT-1080), hamster kidney endothelial (BHK 21) and normal mouse embryonic fibroblasts (NIH 3T3). Most of them were very active against HT-1080 (0.6-5.3 g/ml). Amino acid hydroselenites readily increased the nitric oxide (NO) concentration in the culture medium of HT-1080 cells (up to TG(100)=1500%); however, 4-amidohydroximinomethylpyridinium hydroselenite (TG(100)=24%) and o-phenanthrolinium hydroselenite (TG(100)=50%) were free radical inhibitors. All compounds were glutathione peroxidase inhibitors; some of them could also prevent hydrogen peroxide degradation by inhibition of catalase. The influence of the investigated ammonium hydroselenites on tumor cell (HT-1080) morphology was examined. The substances studied were also active in vivo against sarcoma S-180. The role of organoammonium hydroselenites as free radical regulators and their therapeutic antitumor are discussed.

Abstract
The quaternisation of N-substituted benzimidazoles by heating with various alkyl, allyl, propargyl and benzyl chlorides and bromides leads to the formation of benzimidazolinium salts. The interaction of N-monosubstituted benzimidazoles with various salts (CuCl2, ZnCl2, CoCl2, PdCl2 and AgNO3) yielded stable solid complexes. Potential cytotoxic activity of synthesised benzimidazolinium salts and benzimidazole metal complexes was tested in vitro on four monolayer tumour cell lines: MG-22A (mouse hepatoma), HT-1080 (human fibrosarcoma), B16 (mouse melanoma), Neuro 2A (mouse neuroblastoma) and normal mouse fibroblast cells. A preliminary analysis of the structure-activity relationship for the benzimidazole derivatives clearly indicates that the character of substituents in the benzimidazole ring has strong influence on the cytotoxic activity. The insertion of the silicon atom into the N-alkyl chain increases the cytotoxic activity of benzimidazolinium salts significantly, which show a very significant potency in vitro against all studied tumour cell lines, being particularly active in experiments with B16 (mouse melanoma). TD50 for the most active compounds are in the range 0.001-0.008 microg x ml(-1). Cytotoxicity of benzimidazole metal complexes (L2MX2) strongly depends on the metal nature. 1-(3-trimethylsilylpropyl)benzimidazole in dose 1 mg x kg(-1) inhibits carcinoma S-180 tumour growth by 62% (on ICR mice).
