COL-3-Induced Molecular and Ultrastructural Alterations in K562 Cells
J Pers Med 2022 Jan 4;12(1):42.PMID:35055357DOI:10.3390/jpm12010042.
Tetracycline-3 (4-dedimethylamino Sancycline, COL-3) is a non-antibiotic tetracycline derivative. COL-3 exerts potent anti-metalloproteinase activity and its antitumor effects have been reported both in vitro and in vivo. In this study, we investigated the mechanisms of COL-3-induced cytotoxicity in a chronic myeloid leukemia cell line, K562, characterized by the BCR-ABL fusion protein. COL-3 induced K562 cell death in a concentration-dependent manner with an IC50 of 10.8 µg/mL and exhibited features of both apoptosis and necrosis. However, flow cytometry analysis revealed that necrotic cells dominated over the early and late apoptotic cells upon treatment with COL-3. Transmission electron microscopy analysis in combination with Western blotting (WB) analysis revealed early mitochondrial swelling accompanied by the early release of cytochrome c and truncated apoptosis inducing factor (tAIF). In addition, ultrastructural changes were detected in the endoplasmic reticulum (ER). COL-3 affected the levels of glucose-regulated protein-94 (GRP94) and resulted in m-calpain activation. DNA double strand breaks as a signature for DNA damage was also confirmed using an antibody against γH2AX. WB analyses did not demonstrate caspase activation, while Bcl-xL protein remained unaffected. In conclusion, COL-3-induced cell death involves DNA damage as well as mitochondrial and ER perturbation with features of paraptosis and programmed necrosis.
Comparison of Widely Targeted Metabolomics and Untargeted Metabolomics of Wild Ophiocordyceps sinensis
Molecules 2022 Jun 6;27(11):3645.PMID:35684580DOI:10.3390/molecules27113645.
The authors of this paper conducted a comparative metabolomic analysis of Ophiocordyceps sinensis (OS), providing the metabolic profiles of the stroma (OSBSz) and sclerotia (OSBSh) of OS by widely targeted metabolomics and untargeted metabolomics. The results showed that 778 and 1449 metabolites were identified by the widely targeted metabolomics and untargeted metabolomics approaches, respectively. The metabolites in OSBSz and OSBSh are significantly differentiated; 71 and 96 differentially expressed metabolites were identified by the widely targeted metabolomics and untargeted metabolomics approaches, respectively. This suggests that these 71 metabolites (riboflavine, tripdiolide, bromocriptine, lumichrome, tetrahymanol, citrostadienol, etc.) and 96 metabolites (Sancycline, vignatic acid B, pirbuterol, rubrophen, epalrestat, etc.) are potential biomarkers. 4-Hydroxybenzaldehyde, arginine, and lumichrome were common differentially expressed metabolites. Using the widely targeted metabolomics approach, the key pathways identified that are involved in creating the differentiation between OSBSz and OSBSh may be nicotinate and nicotinamide metabolism, thiamine metabolism, riboflavin metabolism, glycine, serine, and threonine metabolism, and arginine biosynthesis. The differentially expressed metabolites identified using the untargeted metabolomics approach were mainly involved in arginine biosynthesis, terpenoid backbone biosynthesis, porphyrin and chlorophyll metabolism, and cysteine and methionine metabolism. The purpose of this research was to provide support for the assessment of the differences between the stroma and sclerotia, to furnish a material basis for the evaluation of the physical effects of OS, and to provide a reference for the selection of detection methods for the metabolomics of OS.
Preparation and characterization of 4-dedimethylamino Sancycline (CMT-3) loaded nanostructured lipid carrier (CMT-3/NLC) formulations
Int J Pharm 2013 Jun 25;450(1-2):225-34.PMID:23608200DOI:10.1016/j.ijpharm.2013.04.021.
Chemically modified tetracyclines (CMTs) have been reported to strongly inhibit proliferation and metastasis of various cancers, but their efficacy is restricted by poor water solubility. In the present study, a hydrophilic 4-dedimethylamino Sancycline (CMT-3) loaded nanostructured lipid carrier (CMT-3/NLC) was produced by high pressure homogenization (HPH). The physical properties of CMT-3/NLC formulations were characterized by dynamic light scattering (DLS), high efficiency liquid chromatography (HPLC), atomic force microscopy (AFM), scanning electron microscopy (SEM), small-angle neutron scattering (SANS), small-angle X-ray scattering (SAXS) and wide-angle X-ray powder diffraction (XRD). The lipid and surfactant ingredients, as well as drug/lipid concentrations (m/m) were optimized to produce stable and sustained NLC formulations. In vitro cytotoxicity of CMT-3/NLC against HeLa cells was evaluated by MTT assay. The diameter of CMT-3/NLC was found to increase from 153.1±3.0 nm to a maximum of 168.5±2.0 nm after 30 days of storage, while the entrapment efficiency remained constant at >90%. CMT-3/NLC demonstrated a burst-sustained release profile in release media with different pH, a property attributed to the 3-dimensional structure of CMT-3/NLC. Cell uptake and localization studies indicated that NLC reached the cytoplasm and could thereby facilitate CMT-3 entry into HeLa cells.
Comparative study of doxycycline, Sancycline, and 4-dedimethylamino Sancycline (CMT-3) on epidermal melanogenesis
Arch Dermatol Res 2023 Mar;315(2):249-257.PMID:34751807DOI:10.1007/s00403-021-02297-w.
Melanogenesis is regulated by melanocytes, which synthesize the pigment melanin inside melanosomes; these melanosomes are exported through dendritic extensions to adjacent keratinocytes and result in skin coloration. Chemically modified tetracyclines (CMTs) are nonantimicrobial tetracyclines that retain the capacity to inhibit matrix metalloproteinases (MMPs) and have shown several biological benefits; in particular, CMT-3 [(4-dedimethylamino Sancycline (SAN)] has emerged as a candidate for therapeutic benefits in our previous studies. However, to date, studies of the effects of CMT-3 or SAN on melanogenesis are lacking. We have previously reported the anti-melanogenic activity of CMT-308 (the 9-amino derivative of CMT-3). Herein, we have compared the three tetracycline analogs, doxycycline (DOX), SAN, and CMT-3, for their effects on melanogenesis using B16F10 mouse melanoma cells and have validated results in primary human melanocytes (HEMn-DP). DOX did not show any significant effects on intracellular melanin or melanosome export in DP cells while SAN was cytotoxic at high doses but without effects on melanogenesis at lower doses. However, CMT-3 showed a robust suppression of dendricity parameters (dendrite number, dendrite length, and proportion of dendritic cells) in DP cells which was associated, at least in part, with a significant reduction of intracellular tyrosinase activity. In spite of its inhibition of tyrosinase activity, CMT-3 had no significant effects on intracellular melanin levels, suggesting that it selectively targets melanosome export. Our results demonstrate a unique structure-activity relationship (SAR) for the effects of these compounds on melanogenesis and support the conclusion that removal of the 4-dimethylamino moiety confers the selective capacity to suppress melanosome export. Collectively, these results indicate that CMT-3 might be a candidate for diminishing hyperpigmentation skin disorders.
Spectrophotometric determination of acidity constants of 4-dedimethylamino Sancycline (Col-3), a new antitumor drug
J Pharm Sci 1999 May;88(5):535-7.PMID:10229645DOI:10.1021/js980398l.
A spectrophotometric technique was used to determine the acidity constants of 4-dedimethylamino Sancycline (Col-3), a new antitumor drug. The apparent pKa values of Col-3 in 0.5% methanol aqueous media at approximately 25 degrees C with a constant ionic strength of 0.2 were calculated manually and graphically to be 5.64 +/- 0.17 (pKa1) and 8.35 +/- 0.07 (pKa2). In addition, the computer program SQUAD was used to confirm Col-3 pKa values. The pKa values obtained by SQUAD were pKa1 5.63 +/- 0.14 and pKa2 8.39 +/- 0.04. These results are in agreement with the tetracycline-like structure of Col-3.
