Phase 3 Trial of Dichloroacetate in Pyruvate Dehydrogenase Complex Deficiency:

The objective of this research study is to conduct a pivotal phase 3 trial of treatment with the investigational drug dichloroacetate (DCA) in young children with deficiency of the pyruvate dehydrogenase complex (PDC). PDC deficiency (PDCD) is the most common cause of congenital lactic acidosis and is a frequently fatal metabolic disease of childhood for which no proven treatment exists. The investigators predict that DCA represents targeted potential therapy for PDCD because of its ability to increase both the catalytic activity and stability of the enzyme complex. The conclusions of numerous laboratory and clinical investigations are consistent with this postulate and have led to the designation of DCA as an Orphan Product for congenital lactic acidosis by the Food and Drug Administration.
A novel Observer reported outcome (ObsRO) survey that is completed by study participant's parent/caregiver, is the efficacy outcome measure.

Geniposide via enema alleviates colitis by modulating intestinal flora and bile acid metabolites, inhibiting S100A8/S100A9/NF-κB, and promoting TGR5 inhibition of NLRP3 inflammasome

Article

作者: Tian, Jing-Zhuo ; Liu, Mei-Ting ; Zhao, Yong ; Han, Jia-Yin ; Wang, Lian-Mei ; Liu, Su-Yan ; Yi, Yan ; Pan, Chen ; Tang, Xuan ; Wang, Xing-Wen ; Qin, Sha-Sha ; Zheng, Bao-Xin ; Liu, Chen-Yue ; Liang, Ai-Hua ; Li, Chun-Ying

BACKGROUND:

Geniposide (GE) has potential efficacy in treating ulcerative colitis (UC). However, its reactivity can be affected by rapid degradation after oral administration. Furthermore, increasing oral doses may lead to hepatotoxicity. Thus, We used enema administration, characterized by smaller dose and higher localized concentration in the lesion, to improve the above situation.

PURPOSE:

We aimed to confirm that enema administration is a better modality than oral administration for GE against UC and to explore its mechanism.

STUDY DESIGN/METHOD:

We established UC mouse model, monitoring Disease Activity Index (DAI), inflammatory cytokines levels, and histopathology. Macrogenomics and bile acid (BAs) metabolomics analysed the major intestinal flora and BAs. Simultaneouslly, we conducted quantitative proteomics analysis and screened core proteins and pathway. In vitro validation was taken by qPCR, immunofluorescence and immunoblotting experiments.

RESULTS:

GE via enema alleviate UC by inhibiting inflammatory factor production through downregulating S100A8/S100A9/NF-κB pathway. Analysis of the intestinal flora and BAs revealed that the enhanced abundance of Lachnospiraceae, which improves the ratio of primary to secondary BAs, and the reduced abundance of Provocaceae, which increases intestinal permeability and promotes inflammation, favored the restoration of the intestinal barrier. In addition, in vitro experiments confirmed that the key BA metabolites (mainly UDCA, DCA, and LCA) stimulated TGR5 signal to inhibit the assembly of the NLRP3 inflammasome and alleviated inflammation.

CONCLUSION:

We firstly confirmed that GE alleviates UC via the enema route in a better manner than the oral route, through enhancing the intestinal barrier, restoring intestinal flora and BAs homeostasis, and inhibiting inflammatory injury. This study initially revealed that GE can alleviate UC through elevating UDCA, DCA, and LCA levels at the colonic site to activate TGR5 receptor for inhibiting the NLRP3 inflammasome, in addition to downregulating the S100A8/S100A9/-TLR4-NF-κB pathway related inflammatory response directly. The evidences offer a promising strategy and profround meaning for UC treatment.

New insight into intestinal toxicity accelerated by aged microplastics with triclosan: Inflammation regulation by gut microbiota-bile acid axis

Article

作者: Huang, Lu ; Qiao, Qingxia ; Zheng, Li ; Chen, Xiangyu ; Xu, Yanbin ; Lin, Dawu ; Xiong, Kairong ; Zhang, Chaonan ; Lin, Xiaojun ; Liang, Taojie

The combined toxic effects of microplastics (MPs) and their carried contaminants on organisms have been widely concerned; however, the health risks and its mechanism of "gut microbiota-host metabolism (bile acids, BA)" remain unknown. Herein, Xenopus tropicalis were exposured to aged polystyrene MPs carried triclosan (aPS+TCS) and single (a)PS-MPs & TCS, respectively. The bioaccumulation of TCS in the gut of X. tropicalis was significantly increased in aPS+TCS group, which was 89 % higher than that of PS+TCS group, causing more severe oxidative stress, inflammation and intestinal barrier disruption (leaky gut). The expressions of TNF-α, IL-6 and IL-10 in aPS+TCS group were enhanced by 276 % and 19 % and decreased by 81 %, respectively, compared to that in PS+TCS group. Moreover, co-exposure to aPS+TCS increased the number of Escherichia coli, and reduced levels of DCA and LCA (secondary BAs). Multiomics analysis further revealed that the intestinal toxicity of aPS+TCS to X. tropicalis was mainly influenced by the gut flora, BA metabolism and inflammation-related pathways. Co-exposure may exacerbate inflammation by increasing the blood levels of lipopolysaccharides and inhibiting secondary BA production, which are regulated by the gut microbiota-bile acid axis. This study provides new insights in the potential mechanisms of intestinal damage from pollutant-loaded aged MPs.

Covalent sortase A inhibitor, α, β-unsaturated aldehydes, prevents Staphylococcus aureus infection

Article

作者: Peng, Huayong ; Wu, Ziqi ; He, Yuan ; Zhang, Ting ; Chu, Chenliang ; Jin, Lu ; Wang, Jianchao

Sortase A (SrtA) plays a crucial role in the attachment of virulence factors characterized by the LPXTG sequence to the peptidoglycans present on the cell wall surface, thereby rendering it a significant target for anti-virulence agents aimed at combating Staphylococcus aureus (S. aureus) infections. This study focuses on the compound 3, 3'- (1,4-phenylene) diacrylaldehyde (DCA), selected as an anti-anchoring agent for covalent inhibitors. To elucidate the targets of DCA in inhibiting S. aureus and to investigate the molecular mechanism underlying the covalent inhibition of SrtA, proteomics and high-resolution mass spectrometry were employed. The findings indicate that compounds containing α, β-unsaturated aldehydes can covalently modify the catalytic residue Cys184 of SrtA. This modification effectively inhibits the transpeptidation function of SrtA, which is responsible for cell wall anchoring, thereby obstructing the attachment of virulence factors such as IgG-SpA, FnbA, ClfA, Clfb, SdrC, Sas, and Can to the cell wall. As a result, this inhibition impedes immune evasion, biofilm formation, adhesion, and subsequent infection by S. aureus. Furthermore, it disrupts the NADH/NAD⁺ redox homeostasis and diminishes the virulence phenotype by interfering with the glycolytic pathway and the tricarboxylic acid (TCA) cycle of S. aureus. These findings confirm at the molecular level that compounds containing α, β-unsaturated aldehydes possess the potential to serve as anti-virulence drugs that covalently inhibit SrtA.

Saol Therapeutics announces FDA acceptance of New Drug Application for SL1009 for treatment of Pyruvate Dehydrogenase Complex Deficiency

ROSWELL, Ga, DUBLIN and HAMILTON, Bermuda, Jan. 28, 2025 /PRNewswire/ -- Saol Therapeutics, a privately held, clinical-stage pharmaceutical company, announced today that the U.S. Food and Drug Administration (FDA) has accepted for review the New Drug Application (NDA) for SL1009, Sodium Dichloroacetate Oral Solution (DCA). DCA will be used with a proprietary genetic test to treat an orphan pediatric mitochondrial disease, Pyruvate Dehydrogenase Complex Deficiency (PDCD)1. The FDA granted Priority Review for the NDA and has set a goal date of May 27, 2025, under the Prescription Drug User Fee Act (PDUFA). Priority review is designated to applications for drugs that, if approved, would provide a significant improvement in safety or effectiveness of the treatment, prevention or diagnosis of a serious medical condition. SL1009 has previously been granted Orphan Drug and Fast Track Designations. SL1009 has also been granted a Rare Pediatric Disease Designation by the FDA and thus is eligible for a Priority Review Voucher (PRV). PDCD is a rare and life-threatening mitochondrial disorder of carbohydrate oxidation that mostly affects the nervous system and skeletal muscle and leads to decreased ATP production and energy failure. DCA is a targeted therapy that inhibits Pyruvate Dehydrogenase Kinase (PDK) to stimulate residual Pyruvate Dehydrogenase Complex (PDC) activity and increase energy (ATP) production by mitochondria. "This NDA acceptance brings us one step closer to addressing the critical health challenges faced by these children and their families, where no approved treatment is currently available," said Dave Penake, Chief Executive Officer of Saol Therapeutics. "Reaching this regulatory milestone is both a significant scientific achievement and a deeply meaningful moment for everyone who has dedicated themselves to advancing this therapy. Further, designating our application for priority review reaffirms that the FDA views PDCD as a serious condition" The NDA is supported by results from a Phase 3 double-blind placebo-controlled cross-over study (SL1009-01) and a survival study (SL1009-02). The totality of evidence submitted for review in the NDA includes mechanistic characterization, along with nonclinical and clinical evidence to demonstrate the safety and clinical benefit of DCA in PDCD patients. DCA is not currently approved for any indication in the United States. About Pyruvate Dehydrogenase Complex Deficiency (PDCD) PDCD is a mitochondrial disorder of carbohydrate oxidation that mostly affects the nervous system and skeletal muscle and leads to decreased ATP production and energy failure. It is estimated that 300-500 patients are treated in expert centers in the US, and the overall prevalence is thought to be as high as 2,000. PDCD is the most common cause of congenital lactic acidosis, a life-threatening condition that may occur as early as the neonatal period. Patients suffering from PDCD may also exhibit extreme tiredness (lethargy), poor feeding, rapid breathing (tachypnea), and other signs of neurological and neuromuscular dysfunction such as developmental delay, low muscle tone (hypotonia), abnormal eye movements and seizures. Signs and symptoms usually begin soon after birth but may appear later in childhood2. There are currently no FDA-approved therapies for PDCD. About Saol Therapeutics Saol Therapeutics (pronounced "Sail") is a privately held, clinical-stage, pharmaceutical company with operations in Roswell, GA, Dublin, Ireland and Hamilton, Bermuda. Saol is focused on development activity in CNS disorders such as spasticity and pain management, and orphan diseases.
