Carborane clusters act as a synthetic building blocks in the fields of materials science, catalysis and organometallic chemistry. Macromolecular and dendritic drug delivery agents  help in easy accumulation and retention in the tumour tissues due to their unique architectures. Therefore, incorporation of carboranes into dendritic macromolecules provides a valuable approach for the delivery of boron to the tumor tissues for successful treatment of cancer via BNCT. RSC Advances 2020, 10 (57), 34764–34774)

A series of carborane-appended glycoconjugates containing three and six glucose and galactose moieties have been synthesized via Cu(I)-catalyzed azide-alkyne [3+2] click cycloaddition reaction. The evaluation of cytotoxicities and IC50 values of newly synthesized carboranyl glycoconjugates was carried out using two cancerous cell lines (MCF-7 breast cancer cells and A431 skin cancer cells) and one normal cell line (HaCaT skin epidermal cell line). All carboranyl glycoconjugates showed higher cytotoxicities towards cancerous cell lines than the normal cell line. Carboranyl glycoconjugates containing three glucose and galactose moieties were found to be more cytotoxic than the glycoconjugates containing six glucose and galactose moieties. Thus, due to the higher cytotoxicities of dendritic carboranyl glycoconjugates towards cancer cells over healthy cells, they could potentially be useful for bimodal treatment of cancer such as chemotherapy agents and boron neutron capture therapy (BNCT) agents as well. Applied Organometallic Chemistry 2020, 5754-5761

A series of triazine-cored small dendritic molecules containing three to nine peripheral methyl-o-carborane clusters have been synthesized via Cu(I)-catalyzed Huisgen-type azide alkyne cycloaddition reactions (CuAAC). The thermal stability of the dendrimers were rised by increasing of methyl-o-carborane unit at the periphery of dendrimers. The IC50 value of nine cage dendrimer is 80.67 ng/mL which shows most toxic compared to other two carborane dendrimers in MCF-7 cell. Journal of Organometallic Chemistry. 2018, 865, 183-188)

Cyclotriphosphazene core based metallodendrimers containing six and twelve cobalt bis(dicarbollide) moieties on the periphery have been synthesized. The ring opening reaction  of the cyclic oxonium derivative of the cobalt bis(dicarbollide) anion,  [3,3’-Co(8-C4H8O2-1,2-C2B9H10)(1’,2’-C2B9H11)],  has been efficiently used for the synthesis of the dendrimers. The newly synthesized dendrimers have been characterized by 1H, 13C, 11B, 31P NMR and MALDI-TOF mass spectrometry, and the UV-Vis spectroscopy was used to determine the number of Cobaltabis(dicarbollide) units present in the dendrimers molecule. These dendrimers are extremely thermally robust, with 83% and 87% mass retention at 600 oC.
