Agents inducing both apoptosis and autophagic death can be effective chemotherapeutic drugs. In our present work, we synthesized two organometallic gold(III) complexes harboring C^N ligands that structurally resemble tetrahydroisoquinoline (THIQ): Cyc-Au-1 (AuL1Cl2, L1 = 3,4-dimethoxyphenethylamine) and Cyc-Au-2 (AuL2Cl2, L2 = methylenedioxyphenethylamine). In screening their in vitro activity, we found both gold complexes exhibited lower toxicity, lower resistance factors, and better anticancer activity than those of cisplatin. The organometallic gold(III) complexes accumulate in mitochondria and induce elevated ROS and an ER stress response through mitochondrial dysfunction. These effects ultimately result in simultaneous apoptosis and autophagy. Importantly, compared to cisplatin, Cyc-Au-2 exhibits lower toxicity and better anticancer activity in a murine tumor model. To the best of our knowledge, Cyc-Au-2 is the first organometallic Au(III) compound that induces apoptosis and autophagic death. On the basis of our results, we believe Cyc-Au-2 to be a promising anticancer agent or lead compound for further anticancer drug development.

This review, with over 600 references, summarizes the recent applications of photoredox catalysis for organic transformation and polymer synthesis. Photoredox catalysts are metallo- or organo-compounds capable of absorbing visible light, resulting in an excited state species. This excited state species can donate or accept an electron from other substrates to mediate redox reactions at ambient temperature with high atom efficiency. These catalysts have been successfully implemented for the discovery of novel organic reactions and synthesis of added-value chemicals with an excellent control of selectivity and stereo-regularity. More recently, such catalysts have been implemented by polymer chemists to post-modify polymers in high yields, as well as to effectively catalyze reversible deactivation radical polymerizations and living polymerizations. These catalysts create new approaches for advanced organic transformation and polymer synthesis. The objective of this review is to give an overview of this emerging field to organic and polymer chemists as well as materials scientists.

Graphene oxide (GO) has been developed as an inexpensive, environmental friendly, metal-free carbocatalyst for the dehydrogenation of nitrogen heterocycles. Valuable compounds, such as quinoline, 3,4-dihydroisoquinoline, quinazoline, and indole derivatives, have been successfully used as substrates. The investigation of various oxygen-containing molecules with different conjugated systems indicated that both the oxygen-containing groups and large pi-conjugated system in GO sheets are essential for this reaction.

The development of an efficient and economic one-pot process, in which the configuration of the chiral centers of the starting materials is retained, for the preparation of highly pure solifenacin succinate, an antimuscarinic agent, is presented in this communication. The earlier reported processes suffer from the drawbacks of racemization and low yields due to the use of strong base, higher temperatures, and longer reaction times. The present work circumvents these issues by activating (3R)-quinuclidin-3-ol into a mixed active carbonate derivative by treating it with bis(4-nitrophenyl)carbonate. The subsequent reaction of the active carbonate with an enantiomerically pure amine without using any base at ambient temperature provided enantiomerically pure solifenacin with an overall yield of 90%.

We recently demonstrated that SB269652 (1) engages one protomer of a dopamine D2 receptor (D2R) dimer in a bitopic mode to allosterically inhibit the binding of dopamine at the other protomer. Herein, we investigate structural determinants for allostery, focusing on modifications to three moieties within 1. We find that orthosteric “head” groups with small 7-substituents were important to maintain the limited negative cooperativity of analogues of 1, and replacement of the tetrahydroisoquinoline head group with other D2R “privileged structures” generated orthosteric antagonists. Additionally, replacement of the cyclohexylene linker with polymethylene chains conferred linker length dependency in allosteric pharmacology. We validated the importance of the indolic NH as a hydrogen bond donor moiety for maintaining allostery. Replacement of the indole ring with azaindole conferred a 30-fold increase in affinity while maintaining negative cooperativity. Combined, these results provide novel SAR insight for bitopic ligands that act as negative allosteric modulators of the D2R.

A series of 3-alkyl-7-substituted-1,2,3,4-tetrahydroisoquinolines was synthesized and these compounds were evaluated for their PNMT inhibitory potency and affinity for the alpha2-adrenoceptor. 7-Nitro-, 7-bromo-, 7-aminosulfonyl-, or 7-N-2,2,2-trifluoroethylaminosulfonyl-THIQs that possess a 3-alkyl substituent that is longer than a methyl group showed decreased PNMT inhibitory potency, except for 3-propyl-7-aminosulfonyl-THIQ, which displayed excellent PNMT inhibitory potency. The rank order for selectivity (PNMT vs the alpha2-adrenoceptor) is 3-alkyl-7-aminosulfonyl-THIQs ? 3-alkyl-7-N-2,2,2-trifluoroethylaminosulfonyl-THIQs > 3-alkyl-7-nitro-THIQs > 3-alkyl-7-bromo-THIQs.
