Metabolites 2023; 13:934. [PMID: 37623877 PMCID: PMC10456861 DOI: 10.3390/metabo13080934] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2023] [Revised: 07/28/2023] [Accepted: 08/02/2023] [Indexed: 08/26/2023] Open
Abstract
The presence of esterase enzymes in human skin and their role in drug metabolism has been reported, but their distribution in the various skin layers and the relative contributions of those layers to metabolism is poorly defined. To gain further insight into esterase distribution, we performed in vitro skin permeation of a commercial 28.3% methyl salicylate (MeSA) cream (Metsal™) in Franz diffusion cells, using a range of human skin membranes, all from the same donor. The membranes were viable epidermis separated by a dispase II enzymatic method, heat separated epidermis, dermatomed skin, and dermis separated by a dispase II enzymatic method. Methyl salicylate and its metabolite, salicylic acid (SA), were measured by high-performance liquid chromatography. Alpha naphthyl acetate and Hematoxylin and Eosin staining provided qualitative estimations of esterase distribution in these membranes. The permeation of methyl salicylate after 24 h was similar across all membranes. Salicylic acid formation and permeation were found to be similar in dermatomed skin and dermis, suggesting dermal esterase activity. These results were supported by the staining studies, which showed strong esterase activity in the dermal-epidermal junction region of the dermis. In contrast with high staining of esterase activity in the stratum corneum and viable epidermis, minimal stained and functional esterase activity was found in heat-separated and dispase II-prepared epidermal membranes. The results are consistent with dispase II digesting hemidesmosomes, penetrating the epidermis, and affecting epidermal esterases but not those in the dermis. Accordingly, whilst the resulting dispase II-generated dermal membranes may be used for in vitro permeation tests (IVPT) involving esterase-based metabolic studies, the dispase II-generated epidermal membranes are not suitable for this purpose.

Abstract
Coffee silverskin (CS) is the thin epidermis covering and protecting the coffee bean and it represents the main by-product of the coffee roasting process. CS has recently gained attention due to its high content in bioactive molecules and the growing interest in valuable reutilization of waste products. Drawing inspiration from its biological function, here its potential in cosmetic applications was investigated. CS was recovered from one of the largest coffee roasters located in Switzerland and processed through supercritical CO2 extraction, thereby generating coffee silverskin extract. Chemical profiling of this extract revealed the presence of potent molecules, among which cafestol and kahweol fatty acid esters, as well as acylglycerols, β-sitosterol and caffeine. The CS extract was then dissolved in organic shea butter, yielding the cosmetic active ingredient SLVR'Coffee™. In vitro gene expression studies performed on keratinocytes showed an upregulation of genes involved in oxidative stress responses and skin-barrier functionality upon treatment with the coffee silverskin extract. In vivo, our active protected the skin against Sodium Lauryl Sulfate (SLS)-induced irritation and accelerated its recovery. Furthermore, this active extract improved measured as well as perceived skin hydration in female volunteers, making it an innovative, bioinspired ingredient that comforts the skin and benefits the environment.

Abstract
The pharmacokinetics, elimination, and metabolism of fostemsavir (FTR), a prodrug of the HIV-1 attachment inhibitor temsavir (TMR), were investigated in healthy volunteers. FTR was administered with and without ritonavir (RTV), a protease inhibitor previously shown to boost TMR exposures. In vitro studies were also used to identify the enzymes responsible for the metabolism of TMR.Total recovery of the administered dose ranged from 78% to 89%. Approximately 44% to 58% of the dose was excreted in urine, 20% to 36% in feces, and 5% in bile, as TMR and metabolites. RTV had no effect on the recovery of radioactivity in any matrix.Compared to FTR alone, pretreatment of subjects with RTV increased the exposure of TMR by ∼66% and reduced the exposure of plasma total radioactivity by ∼68%.The major route of TMR elimination was through biotransformation. TMR, M28 (N-dealkylation), and M4 (amide hydrolysis) were the major circulating components in plasma. Pretreatment with RTV increased the amount of TMR present, decreased the amount of circulating M28, and M4 was unchanged.CYP3A4 metabolism accounted for 21% of the dose, forming multiple oxidative metabolites. This pathway was inhibited by coadministration of RTV.

Abstract
The breakdown of the epidermal barrier and consequent loss of skin hydration is a feature of skin aging and eczematous dermatitis. Few treatments, however, resolve these underlying processes to provide full symptomatic relief. In this study, we evaluated isosorbide di-(linoleate/oleate) (IDL), which was generated by esterifying isosorbide with sunflower fatty acids. Topical effects of IDL in skin were compared with those of ethyl linoleate/oleate, which has previously been shown to improve skin barrier function. Both IDL and ethyl linoleate/oleate downregulated inflammatory gene expression, but IDL more effectively upregulated the expression of genes associated with keratinocyte differentiation (e.g., KRT1, GRHL2, SPRR4). Consistent with this, IDL increased the abundance of epidermal barrier proteins (FLG and involucrin) and prevented cytokine-mediated stratum corneum degradation. IDL also downregulated the expression of unhealthy skin signature genes linked to the loss of epidermal homeostasis and uniquely repressed an IFN-inducible coexpression module activated in multiple skin diseases, including psoriasis. In a double-blind, placebo-controlled trial enrolling females with dry skin, 2% IDL lotion applied over 2 weeks significantly improved skin hydration and decreased transepidermal water loss (NCT04253704). These results demonstrate mechanisms by which IDL improves skin hydration and epidermal barrier function, supporting IDL as an effective intervention for the treatment of xerotic pruritic skin.

Abstract
Background:
In January 2020, the US FDA published two final guidelines, one entitled “In vitro Drug
Interaction Studies - Cytochrome P450 Enzyme- and Transporter-Mediated Drug Interactions Guidance for Industry”
and the other entitled “Clinical Drug Interaction Studies - Cytochrome P450 Enzyme- and Transporter-Mediated
Drug Interactions Guidance for Industry”. These were updated from the 2017 draft in vitro and clinical DDI
guidance.
Methods:
This study is aimed to provide an analysis of the updates along with a comparison of the DDI guidelines
published by the European Medicines Agency (EMA) and Japanese Pharmaceuticals and Medical Devices Agency
(PMDA) along with the current literature.
Results:
The updates were provided in the final FDA DDI guidelines and explained the rationale of those changes
based on the understanding from research and literature. Furthermore, a comparison among the FDA, EMA, and
PMDA DDI guidelines are presented in Tables 1, 2 and 3.
Conclusion:
The new 2020 clinical DDI guidance from the FDA now has even higher harmonization with the
guidance (or guidelines) from the EMA and PMDA. A comparison of DDI guidance from the FDA 2017, 2020,
EMA, and PMDA on CYP and transporter based DDI, mathematical models, PBPK, and clinical evaluation of DDI
is presented in this review.

Abstract
The effective delivery of menahydroquinone-4 (MKH), an active form of menaquinone-4 (MK-4, vitamin K2(20)), to the skin is beneficial in the treatment of various skin pathologies. However, its delivery through the application of MK-4 to the skin is hampered due to the photoinstability and phototoxicity of MK-4. This study aimed to evaluate the potential of ester prodrugs of MKH for its delivery into the skin to avoid the abovementioned issues. The ester prodrugs, MKH 1,4-bis-N,N-dimethylglycinate hydrochloride (MKH-DMG) and MKH 1,4-bis-hemisuccinate (MKH-SUC), were prepared using our previously reported methods. Photostability was determined under artificial sunlight and multi-wavelength light irradiation, phototoxicity was determined by intracellular ROS formation and cell viability of UVA-irradiated human epidermal keratinocyte cells (HaCaT), and delivery of MKH into HaCaT cells was assessed by measuring menaquinone-4 epoxide (MKO) levels. MKH prodrugs showed higher photostability than MK-4. Although MK-4 induced cellular ROS and reduced cell viability after UVA irradiation, MKH prodrugs did not affect either ROS generation or cell viability. MKH prodrugs enhanced intracellular MKO, indicating effective delivery of MKH and subsequent carboxylation activity. In conclusion, these MKH prodrugs show potential for the delivery of MKH into the skin without photoinstability and phototoxicity.

Abstract
Triptolide (TP) has been used as one of the most common systemic treatments for various diseases since the 1960s. However, TP displays diverse side effects on various organs, which limits its clinical application. To overcome this issue, numerous C-14-hydroxyl group derivatives of TP have been synthesized. In this research, the C-14-hydroxyl group of TP is modified by a cell-penetrating peptide polyarginine (R7). The derivative TP-disulfide-CR7 (TP-S-S-CR7) containing a disulfide linkage between TP and R7 possesses less toxicity at various concentrations on the immortal human keratinocyte (HaCaT) cell line by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay compared with free TP. Treating HaCaT cells with TP (100 nM) could increase intracellular ROS (reactive oxygen species) and decrease the activity of SOD (superoxide dismutase). Meanwhile, treating HaCaT cells with equimolar concentration of TP-S-S-CR7 did not cause both of the above TP-induced alterations. In addition, TP-S-S-CR7 did not show significant dermal toxicity on guinea pigs and could efficiently overcome the barrier of corneum and then reach epidermis and dermis within 2 h of transdermal administration. In addition, there was a relatively lower concentration of TP in blood indicating less toxicity on organs. Such results suggest that topical therapy using polyarginine is possible by the transdermal delivery of TP.

Abstract
![]()
Cancer cells differ
from normal cells in both gain of functions
(i.e., upregulation) and loss of functions (i.e., downregulation).
While it is common to suppress gain of function for chemotherapy,
it remains challenging to target downregulation in cancer cells. Here
we show the combination of enzyme-instructed assembly and disassembly
to target downregulation in cancer cells by designing peptidic precursors
as the substrates of both carboxylesterases (CESs) and alkaline phosphatases
(ALPs). The precursors turn into self-assembling molecules to form
nanofibrils upon dephosphorylation by ALP, but CES-catalyzed cleavage
of the ester bond on the molecules results in disassembly of the nanofibrils.
The precursors selectively inhibit the cancer cells that downregulate
CES (e.g., OVSAHO) but are innocuous to a hepatocyte that overexpresses
CES (HepG2), while the two cell lines exhibit comparable ALP activities.
This work illustrates a potential approach for the development of
chemotherapy via targeting downregulation (or loss of functions) in
cancer cells.
