Abstract
The enzyme chorismate mutase (or CM that is vital for the survival of bacteria) is an interesting pharmacological target for the identification of new anti-tubercular agents. The 5,5-disibstituted pyrazolo[4,3-d]pyrimidinone derivatives containing the fragment based on 4-amino-1-methyl-3-propyl-1H-pyrazole-5-carboxamide were designed and explored as the potential inhibitors of chorismate mutase. Based on encouraging docking results of two representative molecules evaluated in silico against MtbCM (PDB: 2FP2) the Wang resin catalysed sonochemical synthesis of target N-heteroarenes were undertaken. The methodology involved the reaction of 4-amino-1-methyl-3-propyl-1H-pyrazole-5-carboxamide with the appropriate cyclic/acyclic ketones to afford the desired products in acceptable (51-94%) yields. The methodology was also extended successfully towards the synthesis of 2,2-disubstituted 2,3-dihydroquinazolin-4(1H)-ones in excellent (85-90%) yields. In vitro MTT assay against the RAW 264.7 cell line followed by enzymatic assay against MtbCM identified 3b and 3c as active compounds that showed two H-bonding via their NH (at position 6) and CO group with MtbCM in silico and encouraging (54-57%) inhibition at 30 µM in vitro. Notably, none of the 2,2-disubstituted 2,3-dihydroquinazolin-4(1H)-ones showed any significant inhibition of MtbCM suggesting the favourable role of the pyrazole moiety in case of pyrazolo[4,3-d]pyrimidinones. The favourable role of cyclopentyl ring attached to the pyrazolo[4,3-d]pyrimidinone moiety and that of two methyl groups in place of cyclopentyl ring was also indicated by the SAR study. Besides showing effects against MtbCM in the concentration response study, 3b and 3c showed little or no effects on mammalian cell viability up to 100 µM in an MTT assay but decreased the % Mtb cell viability at 10-30 µM with > 20% decrease at 30 µM in an Alamar Blue Assay. Moreover, no adverse effects were noted for these compounds when tested for teratogenicity and hepatotoxicity in zebrafish at various concentrations. Overall, being the only example of MtbCM inhibitors that showed effects on Mtb cell viability the compound 3b and 3c are of further interest form the view point of discovery and development of new anti-tubercular agents.

Abstract
2, 3-Dihydroquinazolinones are of popular compounds with the diversification of biological
and pharmacological activities. Among many discovered methods, there are efficient and convenient
methods used for the synthesis of 2, 3-dihydroquinazoline-4 (1H)-one and some new bis 2, 3-
dihydroquinazoline-4 (1H)-one derivatives which are reported in this study. The mentioned methods
include the two-component condensation of one molecule of anthranilamide and one molecule of pyrazole
carbaldehyde using montmorillonite-K10 as a catalyst for the preparation of 2, 3
dihydroquinazoline-
4 (1H)-ones. Also, one-pot pseudo-five-component reaction (5MCRs) of two molecules of isatoic
anhydride, two molecules of pyrazole carbaldehydes and one molecule of ethan-1, 2-diamine in the
presence of the r catalyst (montmorillonite-K10) for the synthesis of bis 2, 3-dihydroquinazoline-4
(1H)-ones. Despite the short times of reactions, high yields of products were obtained, which were validated
using FT-IR, <sup>1</sup>HNMR, <sup>13</sup>CNMR, and elemental analysis. Moreover, the compounds were
screened for their antimicrobial activities against two-gram-positive bacterial strains: Staphylococcus
aureus and Micrococcus Luteus; and against two-gram-negative bacterial strains, as well: Escherichia
coli and Pseudomonas aeruginosa, which all were utilized for antibacterial investigations. The results
showed moderate or significant antibacterial activities.

Abstract
An elegantly simple, facile, and robust approach to a scaffold of biological importance, 2,3-dihydroquinazolin-4(1H)-ones, is reported. A catalytic 1% SnCl2/microwave-mediated approach afforded access to pure material, collected by cooling and filtration after 20-min microwave irradiation at 120°C. A total of 41 analogues were prepared in isolated yields of 17–99%. This process was highly tolerant of aliphatic, aromatic, heterocyclic, and acyclic aldehydes, but furan, pyrrole, and thiophene aldehyde reactivity correlated with propensity towards electrophilic addition and/or Diels–Alder addition. As a result, thiophene afforded high yields (80%) whereas pyrrole carboxaldehyde failed to react. With simple cinnamaldehydes, and in the SbCl3-mediated reaction, and with α,β-unsaturated aldehydes the equivalent quinazolin-4(3H)-ones, and not the 2,3-dihydroquinazolin-4(1H)-ones, was favoured.
