Abstract
An unprecedented regiodivergent palladium-catalyzed carbonylation of aromatic alkenes has been developed. Utilizing commercially available Pd(CH3 CN)2 Cl2 in the presence of 1,1'-ferrocenediyl-bis(tert-butyl(pyridin-2-yl)phosphine) ligand L8 diverse selenoesters are obtained in a straightforward manner. Key to success for the control of the regioselectivity of the carbonylation step is the concentration of the acidic co-catalyst. This general protocol features wide functional group compatibility and good regioselectivity. Mechanistic studies suggest that the presence of stoichiometric amounts of acid changes the properties and coordination mode of the ligand leading to reversed regioselectivity.

Abstract
In a previous in vitro study, dihydropyrimidinone-derived selenoesteres demonstrated antioxidant properties, metal chelators and inhibitory acetylcholinesterase (AChE) activity, making these compounds promising candidates for Alzheimer's Disease (AD) treatment. However, these effects have yet to be demonstrated in an in vivo animal model; therefore, this study aimed to evaluate the safety and efficacy of eight selenoester compounds in a Caenorhabditis elegans model using transgenic strains for amyloid-beta peptide (Aβ) aggregation. The L1 stage worms were acutely exposed (30 min) to the compounds at concentrations ranging from 5 to 200 μM and after 48 h the maintenance temperature was increased to 25 ° C for Aβ expression and aggregation. After 48 h, several parameters related to phenotypic manifestations of Aβ toxicity and mechanistic elucidation were analyzed. At the concentrations tested no significant toxicity of the compounds was found. The selenoester compound FA90 significantly reduced the rate of paralyzed worms and increased the number of swimming movements compared to the untreated worms. In addition, FA90 and FA130 improved egg-laying induced by levamisole and positively modulated HSP-6 and HSP-4 expression, thereby increasing reticular and mitochondrial protein folding response in C. elegans, which could attenuate Aβ aggregation in early exposure. Therefore, our initial screening using an alternative model demonstrated that FA90, among the eight selenoesters evaluated, was the most promising compound for AD evaluation screening in more complex animals.

Abstract
Tuberculosis (TB) is one of the most fatal diseases and is responsible for the infection of millions of people around the world. Most recently, scientific frontiers have been engaged to develop new drugs that can overcome drug-resistant TB. Following this direction, using a designed scaffold based on the combination of two separate pharmacophoric groups, a series of menadione-derived selenoesters was developed with good yields. All products were evaluated for their in vitro activity against Mycobacterium tuberculosis H37Rv and attractive results were observed, especially for the compounds 8a, 8c and 8f (MICs 2.1, 8.0 and 8.1 μM, respectively). In addition, 8a, 8c and 8f demonstrated potent in vitro activity against multidrug-resistant clinical isolates (CDCT-16 and CDCT-27) with promising MIC values ranging from 0.8 to 3.1 μM. Importantly, compounds 8a and 8c were found to be non-toxic against the Vero cell line. The SI value of 8a (>23.8) was found to be comparable to that of isoniazid (>22.7), which suggests the possibility of carrying out advanced studies on this derivative. Therefore, these menadione-derived selenoesters obtained as hybrid compounds represent promising new anti-tubercular agents to overcome TB multidrug resistance. New menadione-derived selenoesters were synthesized. The compounds demonstrated excellent activity against M. tuberculosis H37Rv. 8a, 8c and 8f showed potent activity against multidrug resistant clinical isolates. Compounds 8a and 8c were found to be non-toxic. These organoselenium compounds represent promising new anti-tubercular agents.

Abstract
BACKGROUND/AIM Selenium-containing compounds are becoming new alternatives in experimental chemotherapy in order to overcome multidrug resistance in cancer. The main goal of this study was to determine whether combined treatment with new Se-compounds would increase the effect of conventional doxorubicin chemotherapy in breast cancer cell lines. MATERIALS AND METHODS Se-compounds were evaluated regarding their cytotoxic and apoptosis-inducing effect on MCF-7 and ATP-binding cassette subfamily B member 1 (ABCB1)-overexpressing KCR breast cancer cell lines. Moreover, the interaction of Se-compounds with doxorubicin was assessed using the MTT assay. RESULTS Selenoanhydride exerted a selective activity towards the doxorubicin-resistant KCR cell line overexpressing ABCB1. Among the selenoesters, only ketone-containing selenoesters exerted significant cytotoxic activity against MCF-7 and KCR cell lines and the Se-compounds acted synergistically with doxorubicin on the KCR cell line. CONCLUSION The importance of the COSeCH2COCH3 and COSeCH2CO(CH3)3 moieties for the cytotoxic and adjuvant role of Se-compounds was highlighted.

Abstract
Taking into account that multidrug resistance (MDR) is the main cause for chemotherapeutic failure in cancer treatment and as a continuation of our efforts to overcome this problem we report the evaluation of one cyclic selenoanhydride (1) and ten selenoesters (2-11) in MDR human colon adenocarcinoma Colo 320 cell line. The most potent derivatives (1, 9-11) inhibited the ABCB1 efflux pump much stronger than the reference compound verapamil. Particularly, the best one (9) was 4-fold more potent than verapamil at a 10-fold lower concentration. Furthermore, the evaluated derivatives exerted a potent and selective cytotoxic activity. In addition, they were strong apoptosis inducers as the four derivatives triggered apoptotic events in a 64-72% of the examined MDR Colo 320 human adenocarcinoma cells.

Abstract
In previous studies, 56 novel selenoesters and one cyclic selenoanhydride with chemopreventive, antiproliferative and cytotoxic activity were described. Herein, the selenoanhydride and selected selenoesters were evaluated for their ability to reverse the cancer multidrug resistance (MDR) using the ABCB1 efflux pump inhibition assay in mouse MDR T-lymphoma cells. Results showed that the selenoanhydride (1) and the selenoesters with ketone terminal fragments (9-11) exerted (1.7-3.6)-fold stronger efflux pump inhibitory action than the reference verapamil. In addition, those four derivatives triggered apoptotic events in more than 80% of the examined MDR mouse cells.
