Malonic acid (also called Propanedioic Acid ) is a white crystalline C-3 dicarboxylic acid; melting at 135 -136 C; readily soluble in water, alcohol and ether; solution in water is medium-strong acidic. It can be derived by oxidizing malic acid or by the hydrolysis of cyanacetic acid. Malonic acid itself is rather unstable and has few applications. Its diethyl ester (diethyl malonate) is more important commercially. Diethyl malonate, a colourless, fragrant liquid boiling at 199 C, is prepared by the reaction of monochloroacetatic acid with methanol, carbon monoxide or by the reaction cyanoacetic acid (the half nitriled-malonic acid) with ethyl alcohol. Malonic acid and its esters contain active methylene groups which have relatively acidic alpha-protons due to H atoms adjacent to two carbonyl groups. The reactivity of its methylene group provide the sequence of reactions of alkylation, hydrolysis of the esters and decarboxylation resulting in substituted ketones. The methylene groups in ...
The demand for new methods through which important enantiopure compounds can be produced is increasing within the chemical industry. In this regard, one group of interesting compounds are enantiopure carboxylic acids as traditional methods towards producing these compounds that rely on a process known as enantioselective decarboxylative protonation (EDP) are often insufficient due to a combination of factors including low yields, low enantioselectivities, the need for environmentally deleterious reaction conditions and high costs. Due to the shortcomings of these synthetic techniques, the application of biological systems is an alternative method that has come to the forefront of current research, which is because biological systems often boast a number of advantages over traditional chemical methods. Described within this thesis is one such biological method towards the production of enantiopure carboxylic acid compounds via EDP, a method that utilises the enzyme aryl malonate decarboxylase ...

Acyltransferase domains control the extender unit recognition in Polyketide Synthases (PKS) and thereby the side-chain diversity of the resulting natural products. The enzyme engineering strategy presented here allows the alteration of the acyltransferase substrate profile to enable an engineered biosynthesis of natural product derivatives through the incorporation of a synthetic malonic acid thioester. Experimental sequence-function correlations combined with computational modeling revealed the origins of substrate recognition in these PKS domains and enabled a targeted mutagenesis. We show how a single point mutation was able to direct the incorporation of a malonic acid building block with a non-native functional group into erythromycin. This approach, introduced here as enzyme-directed mutasynthesis, opens a new field of possibilities beyond the state of the art for the combination of organic chemistry and biosynthesis toward natural product analogues.. ...

Studies were done to determine the mechanism(s) responsible for the thermal lability of adrenal microsomal monooxygenases. Preincubation of guinea pig adrenal microsomal suspensions at 37 degrees C caused large time-dependent declines in benzo(a)pyrene (BP) hydroxylase and benzphetamine (BZ) demethylase activities. Similar preincubations with hepatic microsomes had little effect on enzyme activities. The decreases in adrenal enzyme activities were completely prevented by co-incubation of microsomes with cytosol, but were not diminished by reduced glutathione, ascorbic acid, or bovine serum albumin. Partial protection was afforded by EDTA, suggesting that lipid peroxidation might be involved, but malonaldehyde production was not demonstrable and MnCl2, a potent inhibitor of lipid peroxidation, did not affect the decline in enzyme activities. The decreases in the rates of BP and BZ metabolism were prevented by including NADPH or NADP+ in the preincubation medium. The preincubation conditions ...

If we could realize an autonomous polymer system driven under biological conditions by a tailor-made molecular design, human beings could create unprecedented biomimetic functions and materials such as heartbeats, autonomous peristaltic pumps, etc. In order to achieve this objective, we have investigated the molecular design of such a polymer system. As a result, we were the first to demonstrate a self-oscillating polymer system driven in a solution where only malonic acid existed, which could convert the chemical energy of the Belousov-Zhabotinsky (BZ) reaction into a change in the conformation of the polymer chain. To cause the self-oscillation in solution, we have attempted to construct a built-in system where the required BZ system substrates other than the organic acid are incorporated into the polymer itself. That is, the novel polymer chain incorporated the metal catalyst of the BZ reaction, a pH-control site and an oxidant supply site at the same time. As a result of introducing the pH control
The major findings of the present study are that water-soluble fullerene directly affects vascular ECs to cause cytotoxic injury or cell death and inhibition of cell growth. To the best of our knowledge, this study provides the first demonstration of the direct effects of water-soluble fullerene on vascular endothelium. In other human cells, including dermal fibroblasts, liver carcinoma cells (HepG2), neuronal astrocytes, and T-lymphocytes (Jurkat cells), recent reports have noted that water-soluble fullerene shows cytotoxic effects, presumably via production of reactive oxygen species (22, 24). Notably, several types of water-soluble fullerene derivatives are available [e.g., hydroxyl fullerene used herein, dendritic C60 monoadduct (22), malonic acid C60 (22) and nano-C60 (24) (basically pristine C60)], and cytotoxicity to cells varies depending on the fullerene subtype used, presumably because of surfactant chemistry, including a balance between hydrophobicity and hydrophilicity (3).. Some ...

UNLABELLED: Inhibition of malonyl-coenzyme A decarboxylase (MCD) shifts metabolism from fatty acid towards glucose oxidation, which has therapeutic potential for obesity and myocardial ischemic injury. However, ~40% of patients with MCD deficiency are diagnosed with cardiomyopathy during infancy. AIM: To clarify the link between MCD deficiency and cardiac dysfunction in early life and to determine the contributing systemic and cardiac metabolic perturbations. METHODS AND RESULTS: MCD knockout mice ((-/-)) exhibited non-Mendelian genotype ratios (31% fewer MCD(-/-)) with deaths clustered around weaning. Immediately prior to weaning (18days) MCD(-/-) mice had lower body weights, elevated body fat, hepatic steatosis and glycogen depletion compared to wild-type littermates. MCD(-/-) plasma was hyperketonemic, hyperlipidemic, had 60% lower lactate levels and markers of cellular damage were elevated. MCD(-/-) hearts exhibited hypertrophy, impaired ejection fraction and were energetically compromised (32%

Malotilate is a new drug suggested for use in chronic liver diseases. It is shown here to prevent liver damage caused by CCl4. The concomitant administration of malotilate with CCl4 significantly decreased hydroxyproline accumulation in the liver, liver prolyl 4-hydroxylase and liver and serum galactosylhydroxylysyl glucosyltransferase activities. However, it had no effect on the daily urinary hydroxyproline excretion or the hydroxyproline content of the skin, liver or lungs in normal young growing rats. It also had no specific inhibitory effect on hydroxyproline synthesis or secretion in fibroblast cultures, and did not affect the amount of procollagen-alpha 1(I)-specific mRNAs in these cultures. Thus it seems to have no direct inhibitory effect on collagen metabolism. In addition to inhibition of liver collagen accumulation, malotilate was also able to prevent the development of morphological changes in the liver such as focal necrosis, fatty infiltration and inflammatory changes. It also ...

Malonyl Coenzyme A: A coenzyme A derivative which plays a key role in the fatty acid synthesis in the cytoplasmic and microsomal systems.
800 times higher than carbon dioxide over a 100-year period),3 its discharge into the environment is restricted by the Kyoto Protocol. As a consequence, fluoroform needs to be destroyed or, alternatively, captured and used as a feedstock for manufacturing. The latter option, though vastly preferable, is difficult to realize due to the extraordinarily low reactivity of fluoroform. Only very recently have the first synthetically relevant transformations involving fluoroform started to emerge.4 Most relevant for the present work is a series of seminal publications from the laboratories of Mikami.5-7 Mikami and co-workers have shown that fluoroform can be utilized for the direct difluoromethylation of a variety of substrates utilizing strong lithium bases (lithium diisopropylamide (LDA) or lithium hexamethyldisilazide (LiHMDS)).5-7 In addition to Mikamis work, the difluoromethylation reactions of alkynes with CHF3 and tBuOK,8 as well as the difluoromethylation of phenols and malonates with aqueous ...
Malonate decarboxylase, like citrate lyase, has a unique acyl carrier protein subunit with a prosthetic group derived from, and distinct from, coenzyme A. Members of this protein family are the phosphoribosyl-dephospho-CoA transferase specific to the malonate decarboxylase system. This enzyme can also be designated holo-ACP synthase (2.7.7.61). The corresponding component of the citrate lyase system, CitX, shows little or no sequence similarity to this family ...
