Abstract
A novel series of multifunctional pyrazolo[3,4-d]pyrimidine-based glutamate analogs (6a-l and 7a,b) have been designed and synthesized as antifolate anticancer agents. Among the tested compounds, 6i exhibited the most potent anti-proliferative activity towards NSCLC, CNS, Ovarian, Prostate, Colon, Melanoma, Breast, and Renal cancers with good to weak cytostatic activity and non-lethal actions. 6i demonstrated higher selectivity for cancer than normal cells. 6i could significantly increase the accumulation of S-phase cells during the cell cycle distribution of cancer cells with high potency in the induction of apoptosis. The results unveiled that 6i probably acts through dual inhibition of DHFR and TS enzymes (IC50 = 2.41 and 8.88 µM, correspondingly). Docking studies of 6i displayed that N1-p-bromophenyl and C3-Methyl groups participate in substantial hydrophobic interactions. The drug-likeness features inferred that 6i met the acceptance criteria of Pfizer. Taking together, 6i could be a promising prototype for further optimization as an effective anticancer drug.

Abstract
Molecular rearrangements are important tools to increase the molecular diversity
of new bioactive compounds, especially in the class of heterocycles. This review deals
specifically with a very famous and widely applicable rearrangement known as the Dimroth
Rearrangement. Although it has originally been observed for 1,2,3-triazoles, its amplitude
was greatly expanded to other heterocycles, as well as from laboratory to large
scale production of drugs and intermediates. The reactions that were discussed in this review
were selected with the aim of demonstrating the windows that may be open by the
Dimroth's rearrangement, especially in what regards the development of new synthetic approaches
toward biologically active compounds.

Abstract
Some new 7-alkyl-4,6-dihydropyrazolo[4′,3′:5,6]pyrano[2,3-d]pyrimidin-5(1H)-ones were prepared through heterocyclization of 6-amino-1,4-dihydropyrano[2,3-c]pyrazole-5-carbonitriles with aliphatic carboxylic acids in the presence of phosphoryl chloride under reflux in high yields. The suggested mechanism involves a tandem intramolecular Pinner–Dimroth rearrangement. The products were characterized on the basis of FT-IR, 1H NMR, and 13C NMR spectral and microanalytical data and evaluated for their antibacterial activity against Gram-positive bacteria (Staphylococcus aureus and Staphylococcus epidermidis) and Gram-negative bacteria (Escherichia coli and Pseudomonas aeruginosa) using the disk diffusion method.

Abstract
Two new pyrrolo[2,3-d]pyrimidines (7-deazapurines) were synthesized in high yields by the reaction of 2-amino-1-methyl-4,5-diphenyl-1H-pyrrole-3-carbonitrile with triethyl orthoformate followed by cyclocondensation with methyl or benzyl amine in refluxing glacial acetic acid or using ultrasonic irradiation containing a catalytic amount of glacial acetic acid at 60°C. For each product, the correct structural isomer was identified using the FT-IR, 1H NMR, 13C NMR, 2D nuclear Overhauser effect spectroscopy spectral and microanalytical data together with comparison of the experimental and calculated chemical shifts at the B3LYP/6-31+G(d,p) level of theory. Furthermore, the synthesized compounds were evaluated for their antibacterial activity against Gram-positive bacteria (Staphylococcus aureus and Micrococcus luteus) and Gram-negative bacteria (Escherichia coli) by the agar dilution method using 24-well microtiter plates.

Abstract
A series of pyrazolo[3,4-d]pyrimidine analogues 3, 4, 5a-f, 6a-f with various amines and ester groups at C-4 and N-1 were synthesized and evaluated for antitumour activity. They were also evaluated for xanthine oxidase inhibitory activity, with most compounds having no significant impact. Compound 5e had the strongest activity against human hepatoma carcinoma cells 7402 and 7221, with half-maximal inhibitory concentration values of 4.55 and 6.28, respectively. Structure-activity relationship studies indicate that chlorine atoms in the structure of 4-((4-(substituted amides)phenyl)amino pyrazolo[4,3-d]pyrimidine analogues is crucial for antitumour activity.
