We expand the possibilities in hydrazone based dynamic combinatorial chemistry with a series of new building blocks incorporating heterocyclic motifs. The synthetic procedure allows efficient access to building blocks with the general structure (MeO)2CH-Heterocycle-C(O)NHNH2, originating from heterocycles with an amine and an ester functionality. The equilibrium distribution of macrocyclic N-acyl hydrazones formed upon deprotection of the building blocks with TFA in organic solvents is reported. The mixing behaviour of these heterocycle-based building blocks with our cholate-based building blocks is described, particularly the observation of kinetic intermediates that disappear following ‘proof-reading’.

Analogs of CVFM (a known nonsubstrate farnesyltransferase (FT) inhibitor derived from a CA2A2X sequence where C is cysteine, A is an aliphatic residue, and X is any residue) were prepared where phenylalanine was replaced by (Z)-dehydrophenylalanine, 2-aminoindan-2-carboxylate, 1,2,3,4- tetrahydroisoquinoline-3-carboxylate (Tic), and indoline-2-carboxylate. The greatest improvement in FT inhibitory potency was observed for the Tic derivative (IC50 = 1 nM); however, this compound was ineffective in blocking oncogenic Ras-induced transformation of NIH-3T3 fibroblast cells. A compound was prepared in which both the Cys-Val methyleneamine isostere and the Tic replacement were incorporated. This derivative inhibited FT with an IC50 of 0.6 nM and inhibited anchorage-independent growth of stably transformed NIH-3T3 fibroblast cells by 50% at 5 muM. Replacing the A1 side chain of this derivative with a tert-butyl group and replacing the X position with glutamine led to a derivative with an IC50 of 2.8 nM and an EC50 of 0.19 muM, a 26-fold improvement(S*,R*)-N-[[2-[N-(2-amino-3- mercaptopropyl)-L-valyl]-1,2,3,4-tetrahydro-3-isoquinolinyl]carbonyl]-L- methionine. This derivative, (S*,R*)-N-[[2-[N-(2-amino-3-mercaptopropyl)- L-tert-leucyl]-1,2,3,4-tetrahydro-3-isoquinolinyl]-carbonyl]-L-glutamine, was evaluated in vivo along with (S*,R*)-N-[[2-[N-(2-amino-3-mercaptopropyl)- L-tert-leucyl]-1,2,3,4-tetrahydro-3-isoquinolinyl]carbonyl]-L-methionine methyl ester for antitumor activity in an athymic mouse model implanted ip with H-ras-transformed rat-1 tumor cells. When administered by injection twice a day at 45 mg/kg for 11 consecutive days, both compounds showed prolonged survival time (T/C = 142-145%), thus demonstrating efficacy against ras oncogene-containing tumors in vivo.

-The following derivatives of 1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid have been prepared in their (S)-form and as racemates: hydrochloride of methyl ester, N-carboxy anhydride, and N-acetyl derivative. All the substances were fully characterised by elemental analyses, 1H and 13C NMR spectra, and optical rotation, as the case may be; the N-carboxy anhydride was also characterised by means of X-Ray diffraction. Also identified was the intermediate of the reaction of the title acid with phosgene, the N-chlorocarbonyl derivative, and the respective methyl ester was prepared. The dioxopiperazine of the title acid was prepared and characterised both in pure (S,S)-form and in the form of a mixture of two racemates. The optically pure dioxopiperazine was prepared by a reaction of the N-carboxy anhydride in solid phase.

The use of the tetrahydroisoquinoline scaffold is well documented in biologically active compounds. However, reports of the utilisation of tetrahydroisoquinoline compounds in asymmetric catalysis are limited. The synthesis of novel diamine ligands possessing the tetrahydroisoquinoline (tetrahydroisoquinoline) backbone and evaluation of their activity in the asymmetric transfer hydrogenation of acetophenone are presented. The diamine ligands in conjunction with i-PrOH as the hydrogen source and [RhCl2(Cp*)]2 as the metal precursor proved to be the most effective of the tetrahydroisoquinoline derivatives for this catalytic system. Water was found to have a profound influence on the enantioselectivity of the reaction. Optimisation of the amount water, i-PrOH and catalytic loading content rendered the best result of 70% enantioselectivity for the (S)-1-phenylethanol isomer product.

We report herein the synthesis of new dioxopiperazine isoquinolines using the Pictet-Spengler cyclisation. Our synthetic strategy for the preparation of two new compounds (5, 6), with a tetrahydro-6H-pyrazino[1,2-b]isoquinoline-1,4-dione moiety was developed in only four steps. To understand better the crucial step of the synthesis reported here, theoretical calculations using semiempirical (PM3), ab initio and DFT computations were carried out on a reduced system model. The structure of chlorohydrate water solvate of tetrahydro (2-piperidinylethyl)-6H-pyrazino [1,2-b]isoquinoline-1,4-dione (6·HCl·2H2O) was determined by X-ray diffraction. Theoretical calculations (RHF/3-21G and RB3LYP/6-31G(d)) were also performed for compound 6 neutralised with a chloride ion.
