27. Derivatization of Hyaluronan to Target Neuroblastoma and Neuroglioma Expressing CD44.

Subjects

Abstract

Therapeutics for actively targeting over-expressed receptors are of great interest because the majority of diseased tissues originate from normal cells and do not possess a unique receptor from which they can be differentiated. One such receptor is CD44, which has been shown to be highly overexpressed in many breast cancers and other types of cancer cells. While CD44 has been documented to express low levels in normal adult neurons, astrocytes, and microglia, this receptor may be overexpressed by neuroblastoma and neuroglioma. If differential expression exists between normal and cancerous cells, hyaluronan (HA) could be a useful carrier that targets carcinomas. Thus, HA was conjugated with resveratrol (HA-R), and its efficacy was tested on cortical–neuroblastoma hybrid, neuroblastoma, and neuroglioma cells. Confocal and flow cytometry showed these cells express CD44 and are able to bind and uptake HA-R. The toxicity of HA-R correlated well with CD44 expression in this study. Therefore, conjugating resveratrol and other chemotherapeutics to HA could minimize the side effects for normal cells within the brain and nervous system and could be a viable strategy for developing targeted therapies.

42. Intrinsic low‐dielectric‐constant polyimides based on a novel diamine having −CF3 groups and kinkable 1,4‐diisopropylbenzene units.

Abstract

Polyimides (PIs) with low dielectric constants and optical transparency are of great interest in 5G/6G communication applications and in the microelectronics industry, where they are used as interlayer dielectric materials, wearable display devices and so forth. In this study, we designed and synthesized a novel fluorinated diamine called 4,4′‐(1,4‐phenylenebis(propane‐2,2‐diyl))diphenoxybis(2‐(trifluoromethyl)‐4‐aminobenzene) (BPBTAB) monomer from bisphenol‐P having diisopropyl benzene units and fabricated four novel BPBTAB‐X PIs. These PI films possess excellent properties such as a low dielectric constant (1.13–1.84 at 1 MHz), high 5% loss temperature (395–491 °C), moderate glass transition temperature (223–254 °C), good tensile modulus (0.827–1.076 GPa), excellent optical properties (T450 up to 83.37%), low moisture absorption (<0.63%) and good solubility in organic solvents. Hence, the as‐synthesized PI films exhibit excellent comprehensive properties for high‐frequency 5G/6G communication applications. © 2023 Society of Chemical Industry. [ABSTRACT FROM AUTHOR]
