HYDROXYAPATITE AND PORPHYRIN-FULLERENE NANOPARTICLES FOR DIAGNOSTIC AND THERAPEUTIC DELIVERY OF PARAMAGNETIC IONS AND RADIONUCLIDES

Nanoparticles for drug delivery are the subject of extensive research. Importantly, they can transform in size during synthesis or actual use, thereby changing their cytotoxic properties. The aim of the present work was to study the tendency of [Zn-67] porphyrin-fullerene nanoparticles (BFNP) to aggregate over time and to compare the properties of hydroxyapatite (HAP) nanoparticles obtained through 3 different techniques. We found that aggregation of BFNP nanoparticles does not affect their function but attenuates their cytotoxicity against leukemia cells. We were also able to obtain HAP nanoparticles with programmable properties (such as size, shape or the capacity to adsorb metal ions, ligands and chemical complexes) through enzymatic synthesis by varying its conditions. The synthesized HAP nanoparticles contain short-lived isotopes of zinc and copper (in the form of ions and complexes with pyrimidine or thiazine derivatives). These tumoricidal components (a radionuclide and a ligand or a complex) determine the diagnostic and therapeutic potential of the obtained radiopharmaceutical agents.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 5460-09-3, in my other articles.

Crystal structure, Hirshfeld surface analysis and interaction energy and DFT studies of 3-{(2Z)-2-[(2,4-dichlorophenyl)methylidene]-3-oxo-3,4-dihydro-2H-1,4-benzothiazin-4-yl}propanenitrile

The title compound, C18H12Cl2N2OS, consists of a dihydrobenzothiazine unit linked by a -CH group to a 2,4-dichlorophenyl substituent, and to a propanenitrile unit is folded along the S center dot center dot center dot N axis and adopts a flattened-boat conformation. The propanenitrile moiety is nearly perpendicular to the mean plane of the dihydrobenzothiazine unit. In the crystal, C-H-Bnz center dot center dot center dot N-Prpnit and C-H-Prpnit center dot center dot center dot O-Thz (Bnz = benzene, Prpnit = propanenitrile and Thz = thiazine) hydrogen bonds link the molecules into inversion dimers, enclosing R-2(2) (16) and R-2(2)(12) ring motifs, which are linked into stepped ribbons extending along [110]. The ribbons are linked in pairs by complementary C=O center dot center dot center dot Cl interactions. pi-pi contacts between the benzene and phenyl rings, [centroid-centroid distance = 3.974 (1) angstrom] may further stabilize the structure. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H center dot center dot center dot H (23.4%), H center dot center dot center dot Cl/Cl center dot center dot center dot H (19.5%), H center dot center dot center dot C/C center dot center dot center dot H (13.5%), H center dot center dot center dot N/N center dot center dot center dot H (13.3%), C center dot center dot center dot C (10.4%) and H center dot center dot center dot O/O center dot center dot center dot H (5.1%) interactions. Hydrogen bonding and van der Waals interactions are the dominant interactions in the crystal packing. Computational chemistry calculations indicate that the two independent C-H-Bnz center dot center dot center dot N-Prpnit and CHPrpnit-O-Thz hydrogen bonds in the crystal impart about the same energy (ca 43 kJ mol(-1)). Density functional theory (DFT) optimized structures at the B3LYP/6-311 G(d, p) level are compared with the experimentally determined molecular structure in the solid state. The HOMO-LUMO behaviour was elucidated to determine the energy gap.

Computational strategies to explore antimalarial thiazine alkaloid lead compounds based on an Australian marine sponge Plakortis Lita

In this work, an attempt was made to propose new leads based on the natural scaffold Thiaplakortone-A active against malaria. The 2D QSAR studies suggested that three descriptors correlate with the anti-malarial activity with an R-2 value of 0.814. Robustness, reliability, and predictive power of the model were tested by internal validation, external validation, Y-scrambling, and applicability domain analysis. HQSAR studies were carried out as an additional tool to find the sub-structural fingerprints. The CoMFA and CoMSIA models gave Q(2) values of 0.813 and 0.647, and http://www.w3.org/1999/ values of 0.994 and 0.984, respectively. Using the 2D-QSAR equation, the activity values of the seven modified compounds were calculated and it was found that three molecules showed good anti-malarial activity. Molecular docking of the 42 Thiaplakortone-A derivatives with Plasmodium falciparum calcium-dependent protein kinase 1 (PfCDPK1) was carried out to find out protein-ligand interactions. Data mining of the bioassay data-set AID: 504850 using the classifier based on Random Forest of Weka suggested that all of the eight molecules selected and three out of the seven virtual molecules were anti-malarial active. Both the virtual molecules and drug molecules were docked with CYP3A4, indicating that the virtual molecules could metabolize easily. Toxicity studies using Osiris shows that three molecules showed no toxic characters.

Titania-loaded cellulose-based functional hybrid nanomaterial for photocatalytic degradation of toxic aromatic dye in water

The dispersion of Titania on cellulose nanowhiskers was achieved using titanium tetra-isopropoxide as the precursor and sulphuric acid as a peptizing agent via the low-temperature sol-gel synthesis method. The photocatalytic activity of the resultant hybrid catalyst was studied through photocatalytic removal of toxic aromatic cationic thiazine dye (methylene blue). Diverse instrumental methods used for full characterizations of pristine and prepared materials allowed correlating the type of the chemical moiety incorporated to the formation of Titania-loaded cellulose-based functional nanomaterial as well as its stability and catalytic performance. Results indicated successful synthesis of multiscale Titania (19 nm similar to 1 mu m) and perpetual distribution over cellulose nanowhiskers. The latter showed high photocatalytic behavior towards the degradation of methylene blue (conc. 50 ppm) dye. The degradation reached 98.5 % in 40 min at a reaction rate of 0.188 min(-1) as observed and measured through UV-vis spectrophotometer. Chemical oxygen demand (COD) analysis reveals substantial mineralization of the pollutants by reducing toxicity up to 68.64 % with complete recovery of the catalyst validated by total dissolved solids (TDS) analysis of treated water. Considering the above results, a mechanism has postulated. Kinetic study showed that the degradation reaction obeys pseudo-first-order reaction kinetics with appreciable recyclability after five (05) repeated uses. The results herein open new prospects for cellulose-based functional nanomaterial for various environmental applications.

Synthesis and In Vitro Anticancer Evaluation of Symmetrically Bridged 1,3-thiazine Derivatives

A series of bis-1,3-thiazine derivatives 3a-o were synthesized from the condensation reactions of symmetric dialdehydes 1a-c possessing aliphatic ether spacer units with 3-substituted-amino-2-cyano-3-mercaptoacrylamides 2a-e. The chemical structures of the products were fully characterized by using different spectroscopic techniques, such as H-1 NMR, C-13 NMR, IR, electron impact mass spectrometry, and elemental analysis. Compounds 3a, 3f, and 3k underwent ring opening followed by recyclization and alkylation in basic medium to afford bis-pyrimidinones 4a-c and 5a-c. The anticancer potential of the new bis-1,3-thiazines was assessed in vitro against six different human cell lines, including lung A549, colon HCT116, breast MCF-7, prostate PC3, liver HepG2, and normal melanocyte HFB4. The results revealed a potent activity of compounds 3e and 3k against breast and liver cancer cell lines in comparison with the reference drug doxorubicin with no noticeable toxicity on normal cells.

Novel Maillard Pigment, Furpenthiazinate, Having Furan and Cyclopentathiazine Rings Formed by Acid Hydrolysis of Protein in the Presence of Xylose or by Reaction between Cysteine and Furfural under Strongly Acidic Conditions

A novel Maillard pigment having partial structures of furan and cyclopentathiazine, named furpenthiazinate, was isolated and identified. Although this pigment was found in an acid hydrolysate of a Maillard reaction solution between soy protein and xylose, the same pigment was also formed by the Maillard reaction under strongly acidic conditions between soy protein and xylose and cysteine and furfural. The structure of its reduced form by NaBH4 was determined by MS, NMR, and X-ray analysis and identified as 7-(2-furany1)-2,3,4,4a,5,6-hexahydrocyclopenta[b][1,4]thiazin-4-ium-3-carboxylate, indicating that the chemical structure of furpenthiazinate is 7-(2-furanyl)-2,3,5,6-tetrahydrocyclopenta[b][1,4]thiazine-3-carboxylic acid. Furpenthiazinate showed an absorption maximum at 400 nm and strong yellow color under acidic and neutral conditions. The color contribution of furpenthiazinate was estimated to be more than 60% in a reaction solution prepared from cysteine and furfural.
