Carborane-Containing Hydroxamate MMP Ligands for the Treatment of Tumors Using Boron Neutron Capture Therapy (BNCT): Efficacy without Tumor Cell Entry. Int J Mol Sci 2023; 24:ijms24086973. [PMID: 37108137 PMCID: PMC10139035 DOI: 10.3390/ijms24086973] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2022] [Revised: 03/30/2023] [Accepted: 04/05/2023] [Indexed: 04/29/2023] Open
Abstract
New carborane-bearing hydroxamate matrix metalloproteinase (MMP) ligands have been synthesized for boron neutron capture therapy (BNCT) with nanomolar potency against MMP-2, -9 and -13. New analogs are based on MMP inhibitor CGS-23023A, and two previously reported MMP ligands 1 (B1) and 2 (B2) were studied in vitro for BNCT activity. The boronated MMP ligands 1 and 2 showed high in vitro tumoricidal effects in an in vitro BNCT assay, exhibiting IC50 values for 1 and 2 of 2.04 × 10-2 mg/mL and 2.67 × 10-2 mg/mL, respectively. The relative killing effect of 1 to L-boronophenylalanine (BPA) is 0.82/0.27 = 3.0, and that of 2 is 0.82/0.32 = 2.6, whereas the relative killing effect of 4 is comparable to boronophenylalanine (BPA). The survival fraction of 1 and 2 in a pre-incubation boron concentration at 0.143 ppm 10B and 0.101 ppm 10B, respectively, were similar, and these results suggest that 1 and 2 are actively accumulated through attachment to the Squamous cell carcinoma (SCC)VII cells. Compounds 1 and 2 very effectively killed glioma U87 delta EGFR cells after BNCT. This study is noteworthy in demonstrating BNCT efficacy through binding to MMP enzymes overexpressed at the surface of the tumor cell without tumor cell penetration.

Abstract
The treatment of Parkinson's disease (PD) has not been consistently modified for more than 60 years. L-DOPA, the blood-brain barrier permeable precursor prodrug of dopamine, is to date the only effective therapy on the market. However, it is well known that prolonged treatment with L-DOPA leads to several side effects, which may affect the patient's life expectancy (i.e., the wearing-off phenomenon, on-off fluctuations, and dyskinesia). For this reason, modifications, and supplements to L-DOPA treatment have been and are being studied, which, however, have not yet resulted in a valid alternative to the cornerstone drug. This review aims to summarize the main formulations currently in use for PD treatment, explaining advantages and disadvantages for each class. The attention will be focused on the promising prodrug concept, aimed at finding a suitable L-DOPA substitute with improved pharmacokinetic behavior. In this respect, new potential candidates which show interesting properties for the intended scope, the so-called dicarba-closo-dodecaboranes(12) (carboranes), will be discussed. Carboranes are inorganic molecular icosahedral boron-carbon clusters with 12 vertices and 20 deltahedral faces. They have been extensively studied for applications in medicine as potential pharmacophores, reagents in boron neutron capture therapy (BNCT) and radiotherapy. Here, we discuss them as inorganic scaffolds for dopamine delivery at the central nervous system (CNS) level.

Abstract
Based on the previously reported potent and selective sulfone hydroxamate inhibitors SC-76276, SC-78080 (SD-2590), and SC-77964, potent MMP inhibitors have been designed and synthesized to append a boron-rich carborane cluster by employing click chemistry to target tumor cells that are known to upregulate gelatinases. Docking against MMP-2 suggests binding involving the hydroxamate zinc-binding group, key H-bonds by the sulfone moiety with the peptide backbone residues Leu82 and Leu83, and a hydrophobic interaction with the deep P1' pocket. The more potent of the two triazole regioisomers exhibits an IC50 of 3.7 nM versus MMP-2 and IC50 of 46 nM versus MMP-9.

Abstract
A library of sixteen 2nd generation amino- and amido-substituted carboranyl pyrimidine nucleoside analogs, designed as substrates and inhibitors of thymidine kinase 1 (TK1) for potential use in boron neutron capture therapy (BNCT) of cancer, was synthesized and evaluated in enzyme kinetic-, enzyme inhibition-, metabolomic-, and biodistribution studies. One of these 2nd generation carboranyl pyrimidine nucleoside analogs (YB18A [3]), having an amino group directly attached to a meta-carborane cage tethered via ethylene spacer to the 3-position of thymidine, was approximately 3-4 times superior as a substrate and inhibitor of hTK1 than N5-2OH (2), a 1st generation carboranyl pyrimidine nucleoside analog. Both 2 and 3 appeared to be 5'-monophosphorylated in TK1(+) RG2 cells, both in vitro and in vivo. Biodistribution studies in rats bearing intracerebral RG2 glioma resulted in selective tumor uptake of 3 with an intratumoral concentration that was approximately 4 times higher than that of 2. The obtained results significantly advance the understanding of the binding interactions between TK1 and carboranyl pyrimidine nucleoside analogs and will profoundly impact future design strategies for these agents.

Abstract
Multi-target drug design, in which drugs are designed as single molecules to simultaneously modulate multiple physiological targets, is an important strategy in the field of drug discovery. QT-011, a tamibarotene-furoxan derivative, was here prepared and proposed to exert synergistic effects on antileukemia by releasing nitric oxide and tamibarotene. Compared with tamibarotene itself, QT-011 displayed stronger antiproliferative effects on U937 and HL-60 cells and was more effective evaluated in a nude mice U937 xenograft model in vivo. In addition, QT-011 could release nitric oxide which might contribute to the antiproliferative activity. Autodocking assays showed that QT-011 fits well with the hydrophobic pocket of retinoic acid receptors. Taken together, these results suggest that QT-011 might be a highly effective derivative of tamibarotene and a potential candidate compound as antileukemia agent.

Abstract
This review describes how the incorporation of dicarba-closo-dodecarboranes into half-sandwich complexes of ruthenium, osmium, rhodium and iridium might lead to the development of a new class of compounds with applications in medicine. Such a combination not only has unexplored potential in traditional areas such as Boron Neutron Capture Therapy agents, but also as pharmacophores for the targeting of biologically important proteins and the development of targeted drugs. The synthetic pathways used for the syntheses of dicarba-closo-dodecarboranes-containing half-sandwich complexes of ruthenium, osmium, rhodium and iridium are also reviewed. Complexes with a wide variety of geometries and characteristics can be prepared. Examples of addition reactions on the metal centre, B-H activation, transmetalation reactions and/or direct formation of metal-metal bonds are discussed (103 references).

Abstract
The large diversity of structures and unique bonding modes of organometallic complexes make them possible to act as promising candidate therapeutic agents. In this study, the new type of ferrocene-substituted dithio-o-carborane conjugates (FcSB1, FcSB2, and FcSBCO) has been synthesized, and their in vitro antineoplastic activities have been explored by means of the electrochemical study, the real time cell electronic sensing (RT-CES) system, and biological assays. The conjugate-cell interactions were first monitored by electrochemistry, and the results show different cell uptake efficiency for FcSB1, FcSB2, and FcSBCO toward target cells. Both the highly hydrophobic ferrocenyl and carboranyl groups render the conjugates able to rapidly enter cells and exert acute cytotoxicity after 4 h incubation in serum-free media. However, FcSB1, FcSB2, and FcSBCO display different inhibition efficiencies toward SMMC-7721 and HepG2 cancer cells via the G(0)/G(1) arrest mechanism in a physiological environment. The anticancer activity is in the order FcSB2 > FcSB1 > FcSBCO, which is parallel to the order of the redox potentials of the ferrocenyl groups in the three complexes. In particular, FcSB1 and FcSB2 display a potent selective inhibition effect on the proliferation of the cancer cell lines SMMC-7721 and HepG2, but almost no effect on the normal cell line, the human embryonic lung fibroblast (HELF) cells. Thus, these results may provide some clues for use of the ferrocene-carborane conjugates in developing anticancer drugs.

Abstract
Compounds containing boron atoms play increasingly important roles in the therapy and diagnosis of various diseases, particularly cancer. However, computational drug design of boron-containing therapeutics and diagnostics is hampered by the fact that many software packages used for this purpose lack parameters for all or part of the various types of boron atoms. In the present paper, we describe simple and efficient strategies to overcome this problem, which are based on the replacement of boron atom types with carbon atom types. The developed methods were validated by docking closo- and nido-carboranyl antifolates into the active site of a human dihydrofolate reductase (hDHFR) using AutoDock, Glide, FlexX, and Surflex and comparing the obtained docking poses with the poses of their counterparts in the original hDHFR-carboranyl antifolate crystal structures. Under optimized conditions, AutoDock and Glide were equally good in docking of the closo-carboranyl antifolates followed by Surflex and FlexX, whereas Autodock, Glide, and Surflex proved to be comparably efficient in the docking of nido-carboranyl antifolates followed by FlexX. Differences in geometries and partial atom charges in the structures of the carboranyl antifolates resulting from different data sources and/or optimization methods did not impact the docking performances of AutoDock or Glide significantly. Binding energies predicted by all four programs were in accordance with experimental data.

Abstract
We report the first evidence that boron-containing nucleoside conjugates have a tendency to associate in water solutions. The size, charge, and exoskeletal pattern of the boron cluster can strongly influence the aggregation. The aggregation of nucleosides with attached boron clusters was observed using light scattering and atomic force microscopy techniques. Although the species containing either the bulky amphiphilic [3-cobalt(III) bis(1,2-dicarbollide)]- anion or the electroneutral dicarba-closo-dodecaboranyl moiety tend to form stable nanoparticles in aqueous solutions, the compounds bearing the smaller, negatively charged dicarba-nido-undecaboranyl moiety as well as the unmodified nucleosides do not aggregate. The light scattering measurements also showed that the aggregated species can interact with nonionic surfactant Triton X-100 in solution. The partition coefficients P in the water-octanol system correlate fairly well with the aggregation tendency observed by light scattering measurements. This finding allows us to predict the association behavior of boron-cluster-containing nucleosides on a qualitative level. The observed phenomenon can contribute to a better understanding of biological properties of boronated nucleosides and the design of boronated nucleoside-based drugs such as boron carriers for boron neutron capture therapy of tumors (BNCT) and antiviral agents.

Abstract
Carboranes (dicarba-closo-dodecaboranes) are a class of carbon-containing polyhedral boron-cluster compounds showing remarkable hydrophobic character, chemical and thermal stability, and resistance to catabolism in biological environment. These features allow application of boron clusters as new hydrophobic core structure in biologically active molecules that interact hydrophobically with proteins, thus facilitating new drug design.

Abstract
Different anilides derived from carboxylic acids and substituted anilines have been submitted to the photochemically induced Fries rearrangement giving the corresponding o-amino phenones under conditions that are compatible with the presence of acid-labile groups (such as N-Boc or TBDMSO) on R1 and R3. These compounds, not easily obtained in other ways, are useful building blocks for the preparation of benzocondensated heterocycles. After coupling with N-Boc amino acids and TFA-mediated deprotection, the products cyclized to the corresponding 3,5-disubstituted 1,4-benzodiazepin-2-ones, privileged structures predominantly active in the central nervous system. The same results were obtained by coupling with N-Cbz-protected alpha-amino acids followed by microwave assisted hydrogenolysis. When the Fries rearrangement was carried out on the anilide derived from N-Boc-Ala-OH and the further coupling done with N-Cbz-(OMe)Asp-OH, the formed benzodiazepines could be inserted in a peptide chain for the preparation of conformationally constrained peptidomimetics.

Abstract
Three-dimensional quantitative structure-activity relationship (3D-QSAR) using CoMFA and CoMSIA techniques was applied to evaluate 56 pyrimidine nucleosides as substrates of human thymidine kinase 1 (hTK1), 27 of them containing a carborane substituent either at the 3-, 5-, or 3'-position of the 2'-deoxyuridine scaffold. This is the first report describing 3D-QSAR studies of compounds containing boron atoms. Both CoMFA and CoMSIA models were derived from a training set of 47 molecules and the predictive capacity of the CoMSIA model was successfully validated by accurately calculating known phosphorylation rates of both boronated and non-boron hTK1 substrates that were not included in the training set. The optimal CoMSIA model provided the following values: q(2) 0.622, r(2) 0.983, s 0.165, and F 187.5. Contour maps obtained from the CoMSIA model were in agreement with the experimentally determined biological data.

Abstract
Carboranes (dicarba-closo-dodecaboranes) are a class of carbon-containing polyhedral boron-cluster compounds having remarkable chemical and thermal stability, and hydrophobic character. These features may allow application of carboranes as a new hydrophobic core structure in biologically active molecules that interact hydrophobically with receptors. Here, we report the design and synthesis of novel androgen antagonists bearing a carborane moiety. These compounds, particularly 8a, 8c, and 9d, exhibited anti-androgenic activity similar to that of the well-known anti-androgen flutamide in reporter gene assay using NIH3T3 cells transfected with a human AR expression plasmid. The carborane cage seems to be a privileged hydrophobic pharmacophore for the expression of AR-antagonistic activity.

Abstract
We designed and synthesized novel retinoid X receptor (RXR)-selective antagonists bearing a carborane moiety. Compounds 8a-d or 9a-d themselves have no differentiation-inducing activity toward HL-60 cells and no inhibitory activity towards a retinoic acid receptor (RAR) agonist. However, they inhibit the synergistic activity of an RXR agonist, PA024, in the presence of Am80 on the cell differentiation of HL-60. Transactivation assay using RARs and RXRs suggested that the inhibitory activity of 9b resulted from the selective antagonism at the RXR site of RXR-RAR heterodimers.

We report here the design and synthesis of novel cyclic urea compounds with retinoidal activity. YR105 exhibited potent differentiation-inducing ability toward human promyelocytic leukemia HL-60 cells at the concentration of 10(-9)M: its potency was almost equal to that of the native ligand, all-trans retinoic acid.

Abstract
Computer-aided molecular design (CAMD) of carborane containing compounds is of growing interest for scientists involved in boron neutron capture therapy (BNCT) and other pharmaceutical applications. However, the complex organo-metallic structures of carboranes pose difficulties in modeling and docking of these structures. This is the first report of a new strategy for modeling and docking of carborane containing molecules with the readily available software packages HyperChem, SYBYL and FlexX. It is intended as a guide for boron chemists interested in using CAMD of carborane containing agents for medical applications such as BNCT.
