Wang X, Zhuang Y, Wang Y, Jiang M, Yao L. The recent developments of camptothecin and its derivatives as potential anti-tumor agents. Eur J Med Chem 2023; 260:115710. [PMID: 37595544 DOI: 10.1016/j.ejmech.2023.115710] [Citation(s) in RCA: 11] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2023] [Revised: 07/07/2023] [Accepted: 08/03/2023] [Indexed: 08/20/2023]
Abstract
This review article focuses on the research progress made in the structural modifications of camptothecin (CPT), a potent cytotoxic natural alkaloid. CPT possesses a unique 5-fused ring structure and exhibits various beneficial activities such as anti-proliferative, anti-fungal, insecticidal, and anti-SARS-CoV-2 properties. CPT and its analogs, including Topotecan and Irinotecan, have been successfully developed and marketed as topoisomerase I inhibitors. To enhance the therapeutic potential of CPT, researchers have undertaken structural modifications primarily on the A, B, and E rings of the CPT core structure. These modifications aim to improve the efficacy, selectivity, and pharmacokinetic properties of CPT derivatives. The article reviews the advancements in hybridizing CPT with other bioactive compounds, the synthesis of novel CPT analogs, and their associated biological activities. Moreover, the structure-activity relationship (SAR) of these modified CPT derivatives is summarized to gain insights into their structure-function correlations. In addition to discussing the modifications and biological activities of CPT derivatives, the article also touches upon the mechanism of parent drug release. Many CPT derivatives are prodrugs, meaning they require metabolic activation to generate the active form of the drug. It is a resource for researchers interested in developing novel anti-tumor agents based on CPT, addressing the limitations associated with the parent drug, and exploring various aspects of CPT modifications.

Strategies for Solubility and Bioavailability Enhancement and Toxicity Reduction of Norcantharidin. Molecules 2022; 27:molecules27227740.

Abstract
Cantharidin (CTD) is the main active ingredient isolated from Mylabris, and norcantharidin (NCTD) is a demethylated derivative of CTD, which has similar antitumor activity to CTD and lower toxicity than CTD. However, the clinical use of NCTD is limited due to its poor solubility, low bioavailability, and toxic effects on normal cells. To overcome these shortcomings, researchers have explored a number of strategies, such as chemical structural modifications, microsphere dispersion systems, and nanodrug delivery systems. This review summarizes the structure-activity relationship of NCTD and novel strategies to improve the solubility and bioavailability of NCTD as well as reduce the toxicity. This review can provide evidence for further research of NCTD.

Abstract
Three components of L-ascorbic acid, amino acid and functionalized norcantharidins were constructed together in several steps to form 42 norcantharidin derivatives in a high yield. The structure of these synthesized l-ascorbic acid-amino acid-norcantharidin conjugates are determined by 1HNMR, 13CNMR and MS spectrum. The results showed that compounds 6e, 6g, 6j, 6l, 6m, 6b, 6e, 6i, and 6n showed high cytotoxicity to HepG2 and compounds 6b, 6e-g, 6l, 6n, 7b, 7d, 7h, 7i, 7n, 8g, 8i exhibited high cytotoxicity to SW480; Meanwhile, besides 6b, 6e, 6g, and 6k, the other compounds showed less toxic to LO2 at a concentration of 50 μg/mg after 72 h. Compound 6g can induce Mφ-type macrophages derived from mouse bone marrow to polarize to M1-type macrophages.

Abstract
BACKGROUND Target therapy has been one of the important strategies in new drug discovery and the resulting drug resistance has also been a serious problem for concern. At the same time, there are several cancer genes or pathways operating within a given cancer. Given these two things, the combination therapy will be needed for optimal therapeutic effect. OBJECTIVE Camptothecin and norcantharidin were thus chosen to construct a dual anticancer drugs assemblies mainly because CPT was the DNA-topoisomerase I inhibitor and norcantharidin could also suppress the cancer cell growth by inhibiting protein phosphatase. The designed conjugate of camptothecin and norcantharidin linked by alanine was expected to have dual target drug properties. METHODS EDCI/DMAP was chosen as a coupling agent for the coupling of CPT with substituted norcantharidin derivatives and CCK-8 method was used to test the cytotoxicity and intensity on human hepatoma cell line HepG2. Two kinds of enzymes, Top I and CDC 25B were selected to screen the binding affinity in molecular level. RESULTS Nine of dual targets camptothecin derivatives were smoothly synthesized by twice coupling in the condition of EDCI/DMAP in moderate yield. All of the synthesized compounds were characterized by 1HNMR and 13CNMR spectrum and exhibited strong potent inhibition against Hep G2, SW480, BGC803, and PANC-1 cell line in vitro. The newly synthesized camptothecin compounds, such as 3j and 3i have strengthened inhibition activity compared to camptothecin and norcantharidin. CONCLUSION We have successfully synthesized a series of novel camptothecin derivatives constructed from three components of camptothecin, alanine and norcantharidin. These compounds not only preserved strong activity against several cancer cell lines in vitro, but also exhibited potential binding affinity to target Top I and CDC 25B. Therefore, these conjugates linked by alanine could suppress cancer cell growth by inhibiting Top I and protein phosphatase simultaneously, which makes it much valuable as a novel bi-functional target drug candidate to develop in vivo.
