Abstract
A novel isocyanide-based multicomponent synthesis of alkyl aryl(indol-3-yl)acetimidates has been established. Starting from aryl(indol-3-yl)methylium tetrafluoroborates, aromatic isocyanides and alcohols, the imidates were obtained in moderate to very good yields. Consecutive four-component synthesis of the above mentioned imidates from N-alkylindoles, aromatic aldehydes, aromatic isocyanides and alcohols was also proposed. In addition, it was shown that in the presence of water, aryl(indol-3-yl)methylium tetrafluoroborates reacted with isocyanides to furnish aryl(indol-3-yl)acetamides.

Abstract
Malononitrile is a useful reagent for multicomponent reactions with hundreds of methods developed. In this paper, we suggest α‐(cyano)‐o‐tolunitrile (homophtalonitrile) to work as a vinylogous malononitrile. Thus, a organocatalytic pseudo‐three‐component reaction of homopthalonitrile (2 equiv) and o‐hydroxybenzaldehyde, leading to the diastereoselective formation of 5‐amino‐12H‐chromeno[2,3‐c]isoquinolin‐12‐yl)(cyano)methyl)benzonitriles, was discovered. The possibility to employ other nucleophiles was demonstrated for indoles, and a sequential three‐component reaction of homophtalonitrile, o‐hydroxybenzaldehyde, and (aza)indole, giving 12‐(1H‐Indol‐3‐yl)‐12H‐chromeno[2,3‐c]isoquinolin‐5‐amines, was developed. The photophysical properties of the synthesized compounds have been studied, revealing high fluorescence quantum yields (42–70 %) for indol‐3‐yl substituted 12H‐chromeno[2,3‐c]isoquinolin‐5‐amines and reversible fluorescence quenching under acidic conditions.

Abstract
The sequential three-component reaction between o-hydroxybenzaldehydes, N-(cyanomethyl)pyridinium salts and a nucleophile towards substituted chromenoimidazopyridines under oxidative conditions has been developed. The employment of Mn(OAc)3·2H2O or KMnO4 as stoichiometric oxidants allowed the use of a wide range of nucleophiles, such as nitromethane, (aza)indoles, pyrroles, phenols, pyrazole, indazole and diethyl malonate. The formation of the target compounds presumably proceeds through a domino Knoevenagel/cyclization/Michael addition/oxidative cyclization reaction sequence.

Abstract
The title compound, C25H27NO4 (I), the product of the unusual thermolysis of aza-cyclic allene methyl 10,11-dimeth-oxy-3,8-dimethyl-6-phenyl-3-aza-benzo[d]cyclo-deca-4,6,7-triene-5-carboxyl-ate, represents a bicyclic heterosystem and crystallizes in the monoclinic space group P21/c with three crystallographically independent mol-ecules in the unit cell. These independent mol-ecules adopt very similar geometries and differ only in the conformations of the two meth-oxy substituents on the benzene ring. In two of the three independent mol-ecules, both meth-oxy groups are almost coplanar with the benzene ring [the C-C-O-Me torsion angles are 10.8 (2), 12.3 (2), 9.1 (2) and 13.6 (3)°], whereas in the third mol-ecule, one of the meth-oxy groups is practically coplanar to and the other meth-oxy group is roughly perpendicular to the benzene ring, the C-C-O-Me torsion angles being 14.1 (2) and 76.5 (2)°. The mol-ecule of (I) comprises a fused tetra-cyclic system containing two five-membered rings (cyclo-pentenes) and two six-membered rings (piperidine and benzene). The five-membered rings have the usual envelope conformation, with the methyl-subsituted C atom as the flap in each molecule, and the six-membered piperidine ring has a chair conformation. The methyl substituent at the N atom occupies the sterically favourable equatorial position. The carboxyl-ate group lies almost within the basal plane of the parent cyclo-pentene ring [making dihedral angle of 11.68 (8), 18.94 (9) and 15.16 (9)° in the three independent mol-ecules], while the phenyl substituent is twisted by 48.26 (6), 42.04 (6) and 41.28 (6)° (for the three independent mol-ecules) relative to this plane. In the crystal, mol-ecules of (I) form stacks along the b-axis direction. The mol-ecules are arranged at van der Waals distances.

Abstract
The title compound, C19H19NO5, (I), is the product of a domino reaction between cotarnine chloride and acetyl-acetylene catalysed by copper(I) iodide. The mol-ecule of (I) comprises a fused tetra-cyclic system containing two terminal five-membered rings (pyrrole and 1,3-dioxole) and two central six-membered rings (di-hydro-pyridine and benzene). The five-membered 1,3-dioxole ring has an envelope conformation and the central six-membered di-hydro-pyridine ring adopts a twist-boat conformation. The acyl substituent is almost coplanar with the pyrrole ring, whereas the meth-oxy substituent is twisted by 27.93 (16)° relative to the benzene ring. The 2-oxopropan-1-yl substituent is roughly perpendicular to the pyrrole ring. In the crystal, mol-ecules are stacked along the a-axis direction; the stacks are linked by weak C-H⋯O hydrogen bonds into puckered layers lying parallel to (001).

Abstract
AIM to study changes in the expression of angio- and vasculogenesis markers in colorectal adenocarcinoma metastases to the liver during combined cytotoxic and targeted anti-VEGF therapy versus cytotoxic monotherapy. SUBJECTS AND METHODS Intraoperative samples from 96 patients with colorectal adenocarcinomas metastases to the liver were immunohistochemically examined. The investigation enrolled patients who had preoperatively received either combined FOLFOX6 cytotoxic therapy and targeted anti-VEGF therapy with bevacizumab or only FOLFOX6 therapy, as well as patients who had not received preoperative anti-tumor drug treatment. The expression of SDF1α, CXCR4, CXCR7, and VEGF-A was compared in these groups. Statistical significance was accepted at p<0.05. RESULTS The expression of CXCR4 in the vessel endothelial cells was significantly less frequently detected in the patients who had received combined cytotoxic therapy and targeted anti-VEGF therapy as compared to those had not drug therapy. Comparing the patients treated with cytotoxic drugs with those who had not received anti-tumor therapy revealed similar results in the women. CXCR7 expression in the tumor cells and stromal cells from the metastatic foci was significantly more common in the group of male patients treated with cytotoxic drugs according to the FOLFOX6 regimen. The expression of SDF1α in the tumor cells was significantly more often observed in the male patients who had received combined cytotoxic therapy and targeted anti-VEGF therapy than in those who had not drug therapy. VEGF expression in the stromal cells was significantly less frequently seen in the patients who had received the combined therapy. CONCLUSION Combined cytotoxic therapy and targeted anti-VEGF therapy for colorectal adenocarcinoma metastases to the liver leads to some suppression of the alternative pathway in the formation of new vessels, by reducing the expression of CXCR4 in the vessel endothelial cells and that of VEGF in the stromal cells from the metastatic foci. In men, this therapy simultaneously causes an increase in the expression of SDF1α in the tumor cells and in that of CXCR4 in the stroma. Preoperative FOLFOX6 therapy significantly increases the expression of CXCR7 in the tumor cells and stromal cells in the male patients, which may suggest that this pathway in vessel formation can be activated.

Abstract
AIM To optimize diagnostics and treatment of cystic liver tumors. MATERIAL AND METHODS The analysis included outcomes of 46 patients with liver cystic tumors. RESULTS AND DISCUSSION The use of abdominal Doppler-sonography (37 patients), abdominal contrast-enhanced CT (44 patients) and MRI of abdominal cavity with MR-cholangiography (24 patients) defined radiological semiotics of cystic liver diseases. The most important features of cystic tumors are intraluminal septums with blood flow (82% of patients), solid component (6.8%), daughterly cysts (11.3%), as well as biliary hypertension (39.2% of patients). Research of oncomarkers (CEA, SA 19-9, AFP) in 40 patients showed increased level of SA 19-9 only in case of cystadenocarcinoma and intraductal papillary mucinous neoplasm of biliary type. Benign and malignant cystic tumors had increased contents of oncomarkers in all cases. Surgical treatment was used in 42 patients. Extended liver resections were performed in 10 (23.8%) patients, atypical and anatomical resections (removal of less than 3 segments) - in 31 (73.8%) patients. In one case we applied cryoablation of CA in segment I of the liver in view of invasion into the wall of inferior vena cava and hepatoduodenal ligament. In 2 cases surgery was carried out laparoscopically. Also robot-assisted technique was used in 3 patients. Immunohistochemical study was performed in 22 (44.8%) patients. The diagnosis of CAC and biliary type of IPMN was confirmed in case of high expression of CK7, SK19, MUC1, S100p, SDH2, p53 antibodies. Cystadenomas were associated with moderate expression of ER, PR and p53 antibodies by stroma and CK7, SK19, CDX2, MUC1, S100p antibodies by epithelium. CONCLUSION There are considerable difficulties of differential diagnosis of liver cystic tumors. Therefore, the use of single algorithm of diagnostics and treatment is necessary to confirm accurately the diagnosis at the perioperative stage. Cystic tumor is more likely to be assumed in women with solitary cyst in segment IV of liver. If the diagnosis is suspected or confirmed anatomical liver resection with complete tumor removal is necessary to prevent the recurrence.

Abstract
AIM To improve the results of treatment of a widespread purulent peritonitis in children by optimizing fluid therapy includes the use of combined treatment: reamberin and remaxol. MATERIAL AND METHODS We studied 269 patients aged 1 to 15 years with a widespread purulent peritonitis treated at the children's surgical departments in Samara from 2001 to 2015. The study group included 179 children who used the optimized infusion therapy. In the study group was allocated to 2 groups: 69 children in infusion therapy which used reamberin and 110 patients in which treatment was applied reamberin and remaxol. The surgical treatment used laparoscopic sanation of the abdomen. Comprehensive survey included a study of dynamics of the white blood cell count, leukocyte index Kalf-Caliph, erythrocyte sedimentation rate, temperature, total albumin concentration, transaminase levels. Catamnesis studied 48 patients with the definition of complex intima-media thickness in the projection of basilar, brachial and femoral arteries. RESULTS A study compared indicators of both groups, revealed a more rapid reduction of intoxication symptomps (leukocytosis, LII, body temperature), the disappearance of enteric disease, recovery of protein-synthetic function of the liver, decrease of cytolytic and mesenchymal-inflammatory syndromes in the main group, especially in the subgroup in which treatment was included remaxol. CONCLUSION The use of reamberin and remaxol in infusion therapy led to improvement of the results of the treatment of common purulent peritonitis in children. Study catamnesis with the study of the intima-media revealed that children undergoing widespread purulent peritonitis further develop signs of endothelial dysfunction. The developed clinical recommendations to significantly reduce the risk of developing signs of endothelial dysfunction, thereby reducing the possible appearance of vascular pathology in patients who underwent childhood widespread purulent peritonitis.
