Microbe-host signalling is now a well accepted concept and an intensively studied research field. Although some of the observed bacterial phenotypes are atributed to host-recognition and interkingdom signalling, most of them are not relying on a proved molecular mechanism. Recent progress revealed some recognition and signalling pathways for host molecules in bacterial cells, which try to explain their modulatory e Read More

Every year, cancer takes the life of millions of people. Conventional treatments have produced unsatisfactory results for some types of cancer, and the side effects are extensive, leading to a shift in the focus of treatment towards alternative medicines. Indeed, medicinal plants have long been investigated by scientists for their anti-cancer properties. Some phytochemicals that are important active constituents of plants, includin Read More

A series of secondary amines combining monoterpenoid and aminoadamantane moieties have been synthesized. Their cytotoxic activity against human cancer cells CEM-13, MT-4, and U-937 has been studied for the first time. Most of the obtained compounds exhibited a significant cytotoxic activity with the median cytotoxic dose (CTD50) ranging from 6 to 84 μM. The most promising results were obtained for compound 2b w Read More

A facile and atom-economical boric acid catalyzed direct amidation without any coupling agents for the preparation of Suberoylanilide Hydroxamic Acid (SAHA) and SAHA-based inhibitors targeting anti-proliferation of cancer cells is described. It is applicable to the preparation of SAHAbased inhibitors having an unprotected hydroxyl group in the phenyl ring without the need of the protection. The in-vitro assays data indicate t Read More

Diagnosis of tumour hypoxia is an important aspect in determining the course of tumour therapy. In this study, we developed a novel imaging agent, 99mTcethylenedicysteine- bis-misonidazole (99mTc-EC-MISO), for diagnosing tumour hypoxia. We used 2-nitroimidazole as a reactant to synthesize the amino derivative of misonidazole (MISO) in the first step and then conjugated the di-amino derivative of MISO to the chel Read More

A series of 26 quaternary ammonium pyridoxine derivatives were synthesized and their cytotoxicity and antibacterial activities against clinically relevant bacterial strains were tested in vitro. The antibacterial activity of mono-ammonium salts increased with the rise of the lipophilicity and compound 3,3,5-trimethyl-8,8-dioctyl-1,7,8,9-tetrahydro-[1,3]dioxino[5,4-d]pyrrolo[3,4-b]pyridin-8- ium chloride (2d) reaches a maximu Read More

The diisopentenyloxy quinolobactin derivative 3-methylbut-2-enyl-4-methoxy-8-[(3- methylbut-2-enyl)oxy] quinoline-2-carboxylate, also named as Ppc-1, has been initially isolated from the fruiting bodies of the cellular slime mold Polysphondylium pseudo-candidum. Given that few data are available in the literature concerning the biological properties of this compound, this study was undertaken to evaluate its antibacterial a Read More

We showed di[3,5-diacetyl-1,2,4-triazolbis(4-cyclohexylthiosemicarbazonato) platinum( II)] complex, (W8), endowed with important antitumor properties. Here, we analysed whether W8 can affect human bone marrow-derived Mesenchymal Stem Cells, (hMSCs), involved in tissue repair, immunomodulatory properties and also capacity for homing to injure-tumor sites in ovarian cancer. Specifically, we analysed the effect Read More

Psychotic disorders are complex and caused by interplay of genetic and environmental factors. Influenza is a common infectious disease in humans, and it has been suggested that maternal influenza is an estimated risk factor for psychotic disorders, especially for schizophrenia. In view of conflicting results of this association in literature, we performed the strict meta-analysis to examine whether maternal influenza is a ri Read More

Oxime K203 seems to be the most promising oxime in case of reactivation of tabuninhibited acetylcholinesterase (AChE). Although it was originally developed for treatment of tabun intoxications, it is able to reactivate cholinesterases inhibited by other nerve agents. This study is aimed at the evaluation of its potency in vitro against other nerve agents. For this purpose, sarin, tabun, cyclosarin, soman, VX, Russian VX and DFP w Read More

Objective: Drug resistance from affordable drugs has increased the number of deaths from malaria globally. This problem has raised the requirement to design new drugs against multidrugresistant Plasmodium falciparum parasite. Methods: In the current project, we have focused on four important proteins of Plasmodium falciparum and used them as receptors against a dataset of four anti-malarial drugs. In silico an Read More

A series of palladium complexes with 2,2’-bipyridine and 1-(substituted benzyl) azetidine- 3, 3-dicarboxylates as ligands were synthesized and characterized by IR, 1H-NMR, ESI-MS spectra and elemental analysis. The in vitro cytotoxicity assays were carried out against A549, HCT-116, HepG-2 and SGC7901 cancer cell lines. The result showed that most of the complexes possessed moderate antiproliferative activity agai Read More
