Abstract
Catalysis using supported gold nanoparticles has attracted significant research interest due to their unique properties and potential that is directly related to their particle size. An efficient one-pot, three-component procedure is developed for the preparation of pyrimido[4,5- b][1,6]naphthyridin-4( 1H)-one derivatives (4a–h) by cyclocondensation of 6-amino-2-thioxo-2,3-dihydropyrimidin-4( 1H)-one (1), aromatic aldehydes (2), and 1-benzylpiperidin-4-one (3) in the presence of zeolite-nano Au as a green catalyst in ethanol at 80 °C. The presented methodology has a number of advantages including a reusable catalyst, easy access, short reaction times, high yields, and an easy work-up. The nanogold catalyst is characterized by X-ray diffraction and transmission electron microscopy. The structures of the prepared compounds are established by elemental analyses and spectral data (infrared, mass spectrometry, 1H, and 13C NMR). While molecular docking studies show that products 4a and 4c have binding affinities with the active site of CDKs. A bio-evaluation assay revealed that some of the products exhibit strong to moderate effects against proliferation of Huh7 in an in vitro model of human liver cancer cells as confirmed by morphological alteration. Compounds 4c and 4a offer the lowest IC50 values at 22.5 and 39 µM, respectively.

Abstract
To date, no fused heterocycles have been formed on folic acid molecules; for this reason, and others, our target is to synthesize new derivatives of folic acid as isolated or fused systems. Folic acid 1 reacted with ethyl pyruvate, triethyl orthoformate, ethyl chloroformate, thioformic acid hydrazide, and aldehydes to give new derivatives of folic acid 2-6a,b. Moreover, It reacted with benzylidene malononitrile, acetylacetone, ninhydrin, ethyl acetoacetate, ethyl cyanoacetate, and ethyl chloroacetate to give the pteridine fused systems 10-15, respectively. Ethoxycarbonylamino derivate 5 reacted with some nucleophiles containing the NH2 group, such as aminoguanidinium hydrocarbonate, hydrazine hydrate, glycine, thioformic acid hydrazide, and sulfa drugs in different conditions to give the urea derivatives 16-20a,b. Compound 4 reacted with the same nucleophiles to give the methylidene amino derivatives 21-24a,b. The fused compound 10 reacted with thioglycolic acid carbon disulfide, malononitrile, and formamide to give the four cyclic fused systems 25-30, respectively. The biological activity of some synthesized showed moderate effect against bacteria, but no effect shown towards fungi.

Abstract
In an effort to optimize the structural requirements for combined cytostatic and cytotoxic effects in single agents, a series of 5-(arylthio)-9H-pyrimido[4,5-b]indole-2,4-diamines 3-7 were synthesized and evaluated as inhibitors of receptor tyrosine kinases (RTKs) as well as thymidylate synthase (TS). The synthesis of these compounds involved the nucleophilic displacement of the common intermediate 5-bromo/5-chloro-9H-pyrimido[4,5-b]indole-2,4-diamine with appropriate aryl thiols. A novel four step synthetic scheme to the common intermediate was developed which is more efficient relative to the previously reported six-step sequence. Biological evaluation of these compounds indicated dual activity in RTKs and human TS (hTS). In the VEGFR-2 assay, compound 5 was equipotent to the standard compound semaxanib and was better than standard TS inhibitor pemetrexed, in the hTS assay. Compounds 3, 6 and 7 were nanomolar inhibitors of hTS and were several fold better than pemetrexed.

Abstract
A novel four-component strategy for the efficient synthesis of unprecedented dipyrazolo-fused 2,6-naphthyridines through a double [3 + 2+1] heteroannulation has been described. The bond-forming efficiency, accessibility, and generality of this synthesis make it highly valuable to assemble tetra-heterocyclic scaffolds.

Abstract
Infectious diseases caused by parasites continue to take a massive toll on human health in the poor regions of the world. Filling the anti-infective drug-discovery pipeline has never been as challenging as it is now. The organisms responsible for these diseases have interesting biology with many potential biochemical targets. Inhibition of metabolic enzymes has been established as an attractive strategy for anti-infectious drug development. In this field, dihydrofolate reductase (DHFR) is an important enzyme in nucleic and amino acid synthesis and an extensively studied drug target over the past 50 years. The challenges for novel DHFR inhibition-based chemotherapeutics for the treatment of infectious diseases are now focused on overcoming the resistance problem as well as cost–effectiveness. Each year, the large number of literature citations attest the continued popularity of DHFR. It becomes truly the ‘enzyme of choice for all seasons and almost all reasons’. Herein, we summarize the opportunities and challenges in developing novel lead based on this target.

Abstract
In the mol-ecule of the title compound, C(26)H(22)N(4)S(2), the pyrazole ring is oriented at a dihedral angle of 0.85 (3)° with respect to the adjacent naphthyridine ring, while the other ring of naphthyridine adopts an envelope conformation. The dihedral angle between phenyl and pyrazole rings is 87.65 (3)°. In the crystal structure, weak inter-molecular C-H⋯N inter-actions link the mol-ecules into chains. The π-π contacts between the naphthyridine rings and the naphthyridine and thio-phene rings [centroid-centroid distances = 3.766 (3) and 3.878 (3) Å] may further stabilize the structure. A weak C-H⋯π inter-action is also present.

Abstract
We have tested the hypothesis that 2,4-diamino-6-hydroxymethyl-pteridine (DAP), 2,4-diaminopteroic acid (DAPA), and 2,4 diamino-N10-methyl-pteroic acid (DAMPA) could be converted into aminopterin (from DAP and DAPA) and methotrexate (from DAMPA), both of which are potent inhibitors of dihydrofolate reductase, a proven drug target for Plasmodium falciparum. DAP, DAPA, and DAMPA inhibited parasite growth in the micromolar range; DAMPA was the most active, with 50% inhibitory concentrations in vitro of 446 ng/ml against the antifolate-sensitive strain and 812 ng/ml against the highly resistant strain under physiological folate conditions. DAMPA potentiates the activity of the sulfone dapsone, an inhibitor of dihydropteroate synthase, but not that of chlorcycloguanil, a known inhibitor of dihydrofolate reductase (DHFR). Experiments with a Saccharomyces cerevisiae strain dependent upon the P. falciparum DHFR enzyme showed that DHFR is a target of DAMPA in that system. We hypothesize that DAMPA is converted to methotrexate by the parasite dihydrofolate synthase, which explains the synergy of DAMPA with dapsone but not with chlorcycloguanil. This de novo synthesis will not occur in the host, since it lacks the complete folate pathway. If this hypothesis holds true, the de novo synthesis of the toxic compounds could be used as a framework for the search for novel potent antimalarial antifolates.
