- 2,4-DIOXO-QUINAZOLINE-6-SULFONAMIDE DERIVATIVES AS INHIBITORS OF PARG
-
The present invention relates to compounds of formula I that function as inhibitors of PARG (Poly ADP-ribose glycohydrolase) enzyme activity wherein R1a, R1b, R1c, R1d, R1e, W, X1, X2, X3, X4, X5, X6, X7, c are each as defined herein. The present invention also relates to processes for the preparation of these compounds, to pharmaceutical compositions comprising them, and to their use in the treatment of proliferative disorders, such as cancer, as well as other diseases or conditions in which PARG activity is implicated.

- Productive syntheses of 1-ethynylcyclopropylamine and 1- ethynylcyclobutylamine
-
The new 1,1-dimethylpropargylamine surrogates, 1-ethynylcyclopropylamine (3) and 1-ethynylcyclobutylamine (5), were prepared as hydrochlorides from cyclopropylacetylene and 6-chlorohex-1-yne in overall yields of 39 and 25%, respectively, on a scale of up to 300 mmol. The amine 3 was converted into the new ethynyl-extended 1-aminocyclopropanecarboxylic acid 4, and both the amine 3 as well as the amino acid 4 were made available as their N-Fmoc-protected derivatives.
