Symmetrical star shaped molecules with carborane clusters on the periphery have been synthesized in good yields via silicon tetrachloride mediated cyclotrimerization reactions of 9-benzyl derivatives of carboranes with acetyl group substitution on the benzene ring. Facile functionalization of these symmetrical core structures with 1-iodoheptane and trivinylchlorosilane produce compounds which could be used as liquid crystalline substances and precursors for synthesis of higher order carbosilane dendrons.

Site-Selective Aerobic C-H Monoacylation of Carbazoles Using Palladium Catalysis

Subhadip Maiti, Tirtha Mandal, Barada Prasanna Dash, Jyotirmayee Dash

Summary: This study presents a general palladium-catalyzed monoacylation method for carbazoles, using toluene derivatives as both acyl source and organic solvent, with NHPI and oxygen as cocatalyst and sole oxidant, respectively. The regioselective acylation at C-8 position of monosubstituted N-pyridylcarbazoles is achieved using aldehyde as the acyl source, indicating a highly site-selective acylation proceeding through a radical process.

Summary: In this work, an electrochemical study of the Boron cage monomercaptoundecahydro-closo-dodecaborate [B12H11SH](2-) in solution and in a self-assembled monolayer over a gold electrode was conducted. The study revealed the interaction between the boron cage and the gold surface, formation of a self-assembled monolayer, and the reduction of active sites on the gold surface due to the presence of the boron cage. Bulkier thiols were found to enhance charge accumulation at the electrode-solution interface.

Carborane-Containing Hydroxamate MMP Ligands for the Treatment of Tumors Using Boron Neutron Capture Therapy (BNCT): Efficacy without Tumor Cell Entry

Sebastian Flieger, Mao Takagaki, Natsuko Kondo, Marlon R. Lutz, Yash Gupta, Hiroki Ueda, Yoshinori Sakurai, Graham Moran, Prakasha Kempaiah, Narayan Hosmane, Minoru Suzuki, Daniel P. Becker

Summary: New carborane-bearing hydroxamate matrix metalloproteinase (MMP) ligands with nanomolar potency against MMP-2, -9 and -13 have been synthesized for boron neutron capture therapy (BNCT). In vitro studies showed that these new MMP ligands had high tumoricidal effects in the BNCT assay. This study highlights the importance of targeting MMP enzymes overexpressed on the surface of tumor cells for BNCT efficacy.

Synthesis and anticancer properties of dendritic glycoconjugates containing multiple o-carborane clusters

Summary: Boron-rich glycodendrimers containing multiple glucose moieties and ortho-carborane clusters were synthesized and found to be completely water soluble due to increased hydrophilicity. In vitro evaluation showed that the glycodendrimer with nine glucose moieties exhibited the highest cytotoxicity against MCF-7 breast cancer cells, with a 600-fold higher potency than cisplatin. The study suggests that these glycodendrimers could serve as tumor-specific anticancer agents.

Carboxyboranylamino ethanol: unprecedented discovery of boron agents for neutron capture therapy in cancer treatment

Yinghuai Zhu, Jianghong Cai, Narayan S. Hosmane, Minoru Suzuki, Kazuko Uno, Yingjun Zhang, Mao Takagaki

Summary: Carboxyboranylamino ethanol was prepared with a 75.0% yield through an amine-exchange reaction. It showed lower cytotoxicity and higher anti-tumor efficacy in vitro compared to 4-borono-l-phenylalanine (BPA) and methyl 2-hydroxyl-5-(1'-ortho-carbonylmethyl-1',2',3'-triazol-4'-yl)-benzonate (2). The bio-enhancement was explained using molecular docking calculations.
