3,7-Disubstituted-1,2,3,4-tetrahydroisoquinolines display remarkable potency and selectivity as inhibitors of phenylethanolamine N- methyltransferase versus the alpha2-adrenoceptor(1a)

3-Hydroxymethyl-1,2,3,4-tetrahydroisoquinoline (4) is a more selective inhibitor (PNMT K(i) = 1.1 muM, alpha2 K(i) = 6.6 muM, selectivity (alpha2 K(i)/PNMT K(i)) = 6.0) of phenylethanolamine N-methyltransferase (PNMT, EC 2.1.1.28), with respect to its alpha2-adrenoceptor affinity, than is 3-methyl- 1,2,3,4-tetrahydroisoquinoline (2; PNMT K(i) = 2.1muM, alpha2 K(i) = 0.76 muM, selectivity = 0.36) or 1,2,3,4-tetrahydroisoquinoline (1, THIQ; PNMT K(i) = 9.7 muM, alpha2 K(i) = 0.35 muM, selectivity = 0.036). Evaluation of the O- methyl ether derivative of 4 suggested that the 3-hydroxymethyl substituent might be involved in a hydrogen-bond donor-type of interaction at a sterically compact region in the PNMT active site. The directionality of the steric bulk tolerance at both the PNMT active site and the alpha2-adrenoceptor appears to be the same. Since the presence of a hydrophilic electron- withdrawing substituent (such as NO2, SO2CH3, or SO2NH2) at the 7- position of THIQ reduced the binding affinity toward the alpha2-adrenoceptor, we investigated the combination of both a hydrophilic electron-withdrawing 7- substituent and a 3-alkyl substituent on a THIQ nucleus. A synergistic effect in increasing the PNMT-inhibitory potency of the THIQ nucleus and reducing the affinity toward the alpha2-adrenoceptor was observed with this 3,7- disubstitution. Remarkably, 7-aminosulfonyl-3-hydroxymethyl-THIQ (12; PNMT K(i) = 0.34 muM, alpha2 K(i) = 1400 muM, selectivity = 4100) displayed a 23- 680-fold enhanced selectivity over the parent compounds 27 (SK and F 29661; PNMT K(i) = 0.55 muM, alpha2 K(i) = 100 muM, selectivity = 180) and 4 selectivity = 6.0) and is thus the most selective PNMT inhibitor yet reported.

Synthesis and DNA binding properties of novel benzo[b]isoquino|2,3-h- naphthyridines

Several benzo[b]isoquino[2,3-h]-naphthyridines have been prepared via formal hetero-Diels Alder reaction of N-aryl imines as a key step. These compounds have different side chains at C-11, and a cis or trans configuration at the C-8a,C-14a ring junction. Binding constants for the interaction with oligonucleotides and polynucleotides were determined by UV absorption and melting experiments. NMR experiments (NOE) revealed that the cis isomers, showing a slightly folded structure, preferentially bind to the minor groove of AT-rich oligomers. In contrast, the trans isomers prefer the CG-rich sequences, leading to cap-complexes with the isoquinoline moiety stacked at the top of the double helix, in agreement with the flatter shape, and with a preference for the 3?-terminals, as found for camptothecins. Models of the complexes were built up by molecular dynamics (MD) calculations, by using the inter-proton distances derived from the NOE values. Cytotoxicity assays against human Ewing sarcoma cell lines RD-ES and CAD-ES1 were performed. The Royal Society of Chemistry 2005.

Design and Synthesis of Isoquinolidinobenzodiazepine Dimers, a Novel Class of Antibody-Drug Conjugate Payload

Antibody-drug conjugates (ADCs) represent an important class of emerging cancer therapeutics. Recent ADC development efforts highlighted the use of pyrrolobenzodiazepine (PBD) dimer payload for the treatment of several cancers. We identified the isoquinolidinobenzodiazepine (IQB) payload (D211), a new class of PBD dimer family of DNA damaging payloads. We have successfully synthesized all three IQB stereoisomers, experimentally showed that the purified (S,S)-D211 isomer is functionally more active than (R,R)-D221 and (S,R)-D231 isomers by >50,000-fold and ?200-fold, respectively. We also synthesized a linker-payload (D212) that uses (S,S)-D211 payload with a cathepsin cleavable linker, a hydrophilic PEG8 spacer, and a thiol reactive maleimide. In addition, homogeneous ADCs generated using D212 linker-payload exhibited ideal physicochemical properties, and anti-CD33 ADC displayed a robust target-specific potency on AML cell lines. These results demonstrate that D212 linker-payload described here can be utilized for developing novel ADC therapeutics for targeted cancer therapy.
