DeCure for Combined oxidative phosphorylation deficiency

DeCure's autonomous Rare AI scientist is researching a drug-repurposing hypothesis for combined oxidative phosphorylation deficiency — screening already-approved drugs against its 12-gene Open Targets disease module to publish open-access research. Research is fast; the path to publication is funded in milestone stages.

The disease map

Disease moduleCombined oxidative phosphorylation deficiency maps to a 12-gene Open Targets module — the target space DeCure's AI scientist screens approved drugs against.
DeCure.ai methodSignature reversal (LINCS) plus network proximity (STRING) rank already-approved drugs likely to perturb this module — the same engine that produces DeCure.ai's repurposing hypotheses.
Repurposing thesisScreening approved medicines against this disease module, then publishing the evidence for the strongest candidate. Known pharmacology and human exposure data make the first question sharper — they do not establish safety or efficacy in a new indication.

Current lead

No approved-drug candidate for combined oxidative phosphorylation deficiency is corroborated in the literature DeepSearch retrieved. Some conditions are managed with non-pharmacological care — a device, surgery or physical therapy — rather than a medicine; that may be the case here, or the literature we found may simply be too sparse yet to support a drug-repurposing angle.

Molecular view

latexin (LXN)LXN is one of the genes genetically linked to this disease in Open Targets — shown as context, not as a drug target we're pursuing: no approved-drug candidate for this disease is yet corroborated in the literature we found.

What the evidence adds up to

The 2010 review of combined oxidative phosphorylation deficiencies describes them as a heterogeneous group of often multisystemic and early fatal diseases, among the most common inherited human diseases. These disorders are caused by defects in the OXPHOS system, which comprises five multisubunit enzyme complexes encoded by both nuclear and mitochondrial genomes. The review notes that identifying the genetic defect underlying a combined OXPHOS deficiency is not an easy task, due to the multitude of proteins and intricacy of the processes required for a properly functioning OXPHOS system. The authors state that knowledge of the proteins and processes involved in mitochondrial translation and OXPHOS biogenesis is important for further research into genetic causes, with the ultimate goal to effectively prevent and cure these complex and often devastating disorders.

A 2022 review on targeting OXPHOS in cancer states that OXPHOS takes place in mitochondria and is the process whereby cells use carbon fuels and oxygen to generate ATP. The review notes that it is now clear that OXPHOS, at least in many tumour types, plays a critical role in delivering the bioenergetic and macromolecular anabolic requirements of cancer cells. The review describes current therapeutic approaches and challenges in targeting OXPHOS and the electron transport chain for cancer therapy, but provides no clinical data on any specific drug or outcome in patients.

A 1951 paper describes that low concentrations of 2:4-dinitrophenol (DNP) reversibly uncouple the phosphorylation associated with the oxidation of glutamate. The paper states that DNP prevents the use of energy provided by respiration and glycolysis by inhibiting the formation of high-energy phosphate bonds, and that it accelerates respiration and glycolysis of intact cells. A 1959 paper on oxidative phosphorylation provides no clinical data on any disease or treatment.

No abstract reports any clinical trial, survival data, response rates, or patient outcomes for any drug in combined oxidative phosphorylation deficiency. What is missing is any clinical trial testing a specific intervention in patients with this disease, any validated biomarker for patient stratification, and the funding to move from basic mechanistic description to a therapeutic candidate.

Targeting OXPHOS and the electron transport chain in cancer; Molecular and therapeutic implications

AbstractOxidative phosphorylation (OXPHOS) takes place in mitochondria and is the process whereby cells use carbon fuels and oxygen to generate ATP. Formerly OXPHOS was thought to be reduced in tumours and that glycolysis was the critical pathway for generation of ATP but it is now clear that OXPHOS, at least in many tumour types, plays a critical role in delivering the bioenergetic and macromolecular anabolic requirements of cancer cells. There is now great interest in targeting the OXPHOS and the electron transport chain for cancer therapy and in this review article we describe current therapeutic approaches and challenges.

Mitochondrial Translation and Beyond: Processes Implicated in Combined Oxidative Phosphorylation Deficiencies

AbstractMitochondrial disorders are a heterogeneous group of often multisystemic and early fatal diseases, which are amongst the most common inherited human diseases. These disorders are caused by defects in the oxidative phosphorylation (OXPHOS) system, which comprises five multisubunit enzyme complexes encoded by both the nuclear and the mitochondrial genomes. Due to the multitude of proteins and intricacy of the processes required for a properly functioning OXPHOS system, identifying the genetic defect that underlies an OXPHOS deficiency is not an easy task, especially in the case of combined OXPHOS defects. In the present communication we give an extensive overview of the proteins and processes (in)directly involved in mitochondrial translation and the biogenesis of the OXPHOS system and their roles in combined OXPHOS deficiencies. This knowledge is important for further research into the genetic causes, with the ultimate goal to effectively prevent and cure these complex and often devastating disorders.

The inhibition of oxidative phosphorylation

AbstractLoomis & Lipmann (1948) showed that low concen- trations of 2:4-dinitrophenol (DNP) reversibly un- couple the phosphorylation associated with the oxidation of glutamate. This supported the hypo- thesis that agents such as DNP, which prevent the use of the energy provided by respiration and glycolysis, do so by inhibiting the formation of high- energy phosphate bonds (Lardy & Elvehjem, 1945; McElroy, 1947). The acceleration of respiration and glycolysis of intact cells by low concentrations of DNP (see Meyerhof & Geliazkowa, 1947). Johnson (1941) has suggested that the Pasteur effect is a consequence of the greater efficiency of aerobic phosphorylation compared with that associated with glycolysis, a view which is consistent with the inhibition of the Pasteur effect by DNP (Dodds & Greville, 1934). Lynen (1941) has indeed shown that respiration reduces the amount of orthophosphate available for yeast fermentation.
