Ibuprofen has been reported to possess anticancer activity. In the present work, four ibuprofen conjugates of resorcinarene-Polyamidoamine PAMAM-dendrimers were synthesized with eight or 16 ibuprofen moieties. The ibuprofen was released from the dendrimers in a dependent manner. The drug-conjugated nanoresorcinarene-dendrimers showed higher cellular uptake than free ibuprofen. In vitro cytotoxicity studies were performed with free ibuprofen and with the synthesized conjugates in U251, PC-3, K-562, HCT-15, MCF-7, SKLU-1, and MDA U251 (human glioblastoma), PC-3 (human prostatic adenocarcinoma), K-562 (human chronic myelogenous leukemia cells), HCT-15 (human colorectal adenocarcinoma), MCF-7 (human mammary adenocarcinoma), SKLU-1 (human lung adenocarcinoma), and MDA-MB-231 (human mammary adenocarcinoma) cancer cell lines by different cytotoxicity assays. Ibuprofen conjugates of the first and second generations showed significant cytotoxic effects towards the human glioblastoma (U251) and human mammary adenocarcinoma (MCF-7, MDA) cell lines. Moreover, the ibuprofen conjugates improved cytotoxicity compared to free ibuprofen. Increased therapeutic efficacy was observed with specific ibuprofen conjugates of the second generation using low doses.

After understanding the biological signaling roles of hydrogen sulfide and its involvement in various physiological processes, there has been enormous interest in exploring its therapeutic utility in areas such as cancer, inflammation, cardiovascular diseases, etc. There is also growing interest in using suitable HS donors in combination with other drugs to improve the treatment outcome through the modulation of multiple pathways. The premature release of HS from small molecule donors and the difficulty in controlling its spatio-temporal distribution are the major challenges during these efforts.

Ibuprofen (IBU) is a significant contaminant frequently found in wastewater treatment plants due to its widespread use and limited removal during treatment processes. This leads to its discharge into the environment, causing considerable environmental concerns. The use of microorganisms has recently been recognized as a sustainable method for mitigating IBU contamination in wastewater.

Objective: The development of an efficient, multifunctional drug delivery system overcoming different obstacles generally associated with drug formulations, including the poor accumulation of the active principle in the target site and its sustained release for prolonged time.
Methods: Our study proposes the development of a fluorinated poly(amidoamine) (PAMAM) carrier prodrug combining drug release boosted in alkaline environments with a possible implementation in F MRI applications. In particular, we functionalized the terminal primary amines of PAMAM G2 and G4 through an ad hoc designed fluorinated ibuprofen-arginine Michael acceptor to obtain multifunctional ibuprofen-PAMAM-Arg conjugates.

The purpose of this study was to examine how the introduction of ibuprofen (IBU) affected tumor-targeting and biodistribution properties of Lu-labeled IBU-conjugated alpha-melanocyte-stimulating hormone peptides. The IBU was used as an albumin binder and conjugated to the DOTA-Lys moiety without or with a linker to yield DOTA-Lys(IBU)-GG-Nle-CycMSH {1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid-Lys(IBU)-Gly-Gly-Nle-c[Asp-His-DPhe-Arg-Trp-Lys]-CONH}, DOTA-Lys(Asp-IBU)-GGNle-CycMSH, DOTA-Lys(Asn-IBU)-GGNle-CycMSH, and DOTA-Lys(Dab-IBU)-GGNle-CycMSH peptides. Their melanocortin-receptor 1 (MC1R) binding affinities were determined on B16/F10 melanoma cells first.

The most effective anticancer drugs currently entail substantial and formidable side effects, and resistance of tumors to chemotherapeutic agents is a further challenge. Thus, the search for new anticancer drugs as well as novel therapeutic methods is still extremely important. Non-steroidal anti-inflammatory drugs (NSAIDs) can inhibit COX (cyclooxygenase), overexpressed in some tumors.
