Anti-biofilm Fe3O4@C18-[1,3,4]thiadiazolo[3,2-a]pyrimidin-4-ium-2-thiolate Derivative Core-shell Nanocoatings.

ABSTRACT: The derivatives 5,7-dimethyl[1,3,4]thiadiazolo[3,2-a]pyrimidin-4-ium-2-thiolate (1) and 7-methyl-5-phenyl[1,3,4]thiadiazolo[3,2-a]pyrimidin-4-ium-2-thiolate (2) were fully characterized by single-crystal X-ray diffraction. Their supramolecular structure is built through both ?-? stacking and C=S-? interactions for both compounds. The embedment of the tested compounds into Fe3O4@C18 core-shell nanocoatings increased the protection degree against Candida albicans biofilms on the catheter surface, suggesting that these bioactive nanocoatings could be further developed as non-cytotoxic strategies for fighting biofilm-associated fungal infections.

Bis[2-(pyrimidin-2-ylamino)pyrimidin-ium] hexa-molybdate.

Project description:The title compound, (C(8)H(8)N(5))(2)[Mo(6)O(19)], was prepared by reaction of Mo(CO)(6) and dipyrimidylamine in refluxing toluene. The hexa-nuclear polyoxomolybdate anions lie on centres of inversion. Each 2-(pyrimidin-2-ylamino)pyrimidinium cation forms an intra-molecular N-H⋯N hydrogen bond and the cations are linked through self-complementary pairs of N-H⋯N hydrogen bonds into dimers across centres of inversion. The cations and anions are inter-linked through C-H⋯O contacts.

N-Benzyl-thieno[3,2-d]pyrimidin-4-amine.

Project description:The title compound, C13H11N3S, crystallizes with two independent mol-ecules in the asymmetric unit. The two mol-ecules are geometrically very similar and differ mainly in a spatial orientation of the benzene and thieno[3,2-d]pyrimidine ring systems [dihedral angles = 69.49?(4) and 79.05?(3)°]. The nine-membered thieno[3,2-d]pyrimidine moieties have a planar conformation (r.m.s. deviations = 0.020 and 0.012?Å). In the crystal, mol-ecules are linked through N-H?N, N-H?C and C-H?? non-covalent contacts into chains along the c axis, while neighbouring chains are connected via C-H?N inter-actions.

Bis(2,6-diamino-4-chloro-pyrimidin-1-ium) fumarate.

Project description:In the title salt, 2C4H6ClN4(+)·C4H2O4(2-), the complete fumarate dianion is generated by crystallographic inversion symmetry. The cation is essentially planar, with a maximum deviation of 0.018 (1) Å. In the anion, the carboxyl-ate group is twisted slightly away from the attached plane, the dihedral angle between the carboxyl-ate and (E)-but-2-ene planes being 12.78 (13)°. In the crystal, the protonated N atom and the 2-amino group of the cation are hydrogen bonded to the carboxyl-ate O atoms of the anion via a pair of N-H⋯O hydrogen bonds, forming an R2(2)(8) ring motif. In addition, another type of R2(2)(8) motif is formed by centrosymmetrically related pyrimidinium cations via N-H⋯N hydrogen bonds. These two combined motifs form a heterotetra-mer. The crystal structure is further stabilized by stong N-H⋯O, N-H⋯Cl and weak C-H⋯O hydrogen bonds, resulting a three-dimensional network.

Green synthesis and characterisation of novel [1,3,4]thiadiazolo/benzo[4,5]thiazolo[3,2-a]pyrimidines via multicomponent reaction using vanadium oxide loaded on fluorapatite as a robust and sustainable catalyst.

Project description:We synthesised materials with different loadings of vanadia on fluorapatite (V2O5/FAp), fully characterised their structural properties using various spectral techniques including TEM, BET, XRD, FT-IR, SEM and EDX and assessed their prowess as catalysts. The 2.5% V2O5/FAp exhibited excellent activity for the synthesis of novel [1,3,4]thiadiazolo[3,2-a]pyrimidines and benzo[4,5]thiazolo[3,2-a]pyrimidines. The one-pot three-component fusion reaction between chosen substrates of 1,3,4-thiadiazole-amines or 2-amino-benzothiazole, aldehydes and active methylene compounds in ethanol solvent at room temperature gave an excellent yield of products (90-97%) in a swift reaction (25-30 min). The advantages of this protocol are rapid synthesis, mild reaction conditions, green solvent, easy work-up, eco-friendliness, reusability of catalyst and no need for column chromatography.

Project description:Herein, we report an environmentally friendly, rapid, and convenient one-pot ultrasound-promoted synthesis of 5-amino-2-(4-chlorophenyl)-7-substituted phenyl-8,8a-dihydro-7H-(1,3,4)thiadiazolo(3,2-?)pyrimidine-6-carbonitrile derivatives. The in-vitro anticancer activities of these compounds were evaluated against four human tumor cell lines. Among all the synthesized derivatives, compound 4i, which has substituent 3-hydroxy-4-methoxyphenyl is found to have the highest GI50 value of 32.7 ?M, 55.3 ?M, 34.3 ?M, 28.9 ?M for MCF-7, K562, HeLa and PC-3 cancer cell lines respectively. A docking study of the newly synthesized compounds were performed, and the results showed good binding mode in the active site of thymidylate synthase enzyme. ADME properties of synthesized compounds were also studied and showed good drug like properties.

Bis(2,4,6-tri-amino-pyrimidin-1-ium) sulfate penta-hydrate.

Project description:The asymmetric unit of the title salt, 2C4H8N5 (+)·SO4 (2-)·5H2O, contains four 2,4,6-tri-amino-pyrimidinium (TAPH(+)) cations, two sulfate anions and ten lattice water mol-ecules. Each two of the four TAPH(+) cations form dimers via N-H⋯N hydrogen bonds between the amino groups and the unprotonated pyrimidine N atoms [graph-set motif R 2 (2)(8)]. The (TAPH(+))2 dimers, in turn, form slightly offset infinite π-π stacks parallel to [010], with centroid-centroid distances between pyrimidine rings of 3.5128 (15) and 3.6288 (16) Å. Other amino H atoms, as well as the pyrimidinium N-H groups, are hydrogen-bonded to sulfate and lattice water O atoms. The SO4 (2-) anions and water mol-ecules are inter-connected with each other via O-H⋯O hydrogen bonds. The combination of hydrogen-bonding inter-actions and π-π stacking leads to the formation of a three-dimensional network with alternating columns of TAPH(+) cations and channels filled with sulfate anions and water mol-ecules. One of the sulfate anions shows a minor disorder by a ca 37° rotation around one of the S-O bonds [occupancy ratio of the two sets of sites 0.927 (3):0.073 (3)]. One water mol-ecule is disordered over two mutually exclusive positions with an occupancy ratio of 0.64 (7):0.36 (7).

Crystal structure of 2-acetyl-5-(3,4-di-meth-oxy-phen-yl)-6-eth-oxy-carbonyl-3,7-dimethyl-5H-thia-zolo[3,2-a]pyrimidin-8-ium chloride.

Project description:The title mol-ecular salt, C21H25N2O5S(+)·Cl(-), crystallizes with two ion pairs in the asymmetric unit. The cations have similar conformations (r.m.s. overlay fit = 0.40 Å), with one of them showing disorder of the terminal methyl group of the ester in a 0.72 (2):0.28 (2) ratio. In the first cation, the 3,4-dimeth-oxy-substituted phenyl ring subtends a dihedral angle of 88.38 (7)° with the pyrimidine ring and 6.79 (8)° with the thia-zole ring. The equivalent data for the second cation are 89.97 (3) and 6.42 (7)°, respectively. The pyrimidine ring adopts a sofa conformation in each cation. In the crystal, the components are linked by N-H⋯Cl hydrogen bonds, generating isolated ion pairs. The ion pairs are are linked by C-H⋯O inter-actions, generating a three-dimensional network. In addition, a weak C-H⋯π inter-action is observed.
