bioinorganic chemistry @UBB

Welcome to Prof. Radu Silaghi-Dumitrescu's research group page at the Faculty of Chemistry and Chemical Engineering, Babes-Bolyai University. We are an enthusiastic team focused on bioinorganic chemistry - and especially metalloproteins - at UBB since 2006.


We are interested especially in small molecule activation at bioinorganic systems containing transition metals (heme proteins, non-heme iron cobalamin, copper-containing proteins, model systems and others) as well as on oxidative/nitrosative stress especially when pertaining to bioinorganic centers and biologically-relevant free radical chemistry.


We typically employ methods such as UV-vis, EPR, stopped-flow, freeze-quench, molecular biology, protein overexpression and purification, as well as molecular modelling (DFT, semiempirical, molecular dynamics, docking and others).

Meet Our Team

Our main labs are in rooms 56 (stopped-flow, UV-vis, student office), 2 (EPR), and 80 (prof's office) at the Faculty of Chemistry and Chemical Engineering, UBB, downtown Cluj-Napoca.

A number of other students do occasional internships in our group. We also welcome occasional visitors.
A few of our current research projects:
Blood Substitutes
The blood currently used in transfusions presents problems linked to stability (requiring refrigeration and becoming outdated after about a month), availability (especially under crisis situations, such as major accidents, military situations, or major outbreaks), antigens (blood group compatibility), contamination (AIDS, hepatitis, or agents yet to be identified) or ethics (e.g., Jehovah's witnesses). Blood substitutes are chemical or biochemical preparations aimed at being used in transfusions without the above-mentioned drawbacks and with the sole role of enhancing oxygen transport by the patient's blood (as opposed to the more complex functions that blood normally achieves, such as transport or defense).

There are three classes of blood substitutes currently being debated in the scientific literature. The first two classes represent purely synthetic approaches, while the third is semi synthetic, employing the hemoglobin already produced by living organisms. We have recently added a fourth class of blood substitutes, whose active ingredient is also a protein specialized in oxygen transport, but of non-heme nature: hemerythrin (Hr). Hr employs a binuclear non-heme diferrous center to bind oxygen; the resulting adduct is formally described as Fe(III)-Fe(III)-OOH, i.e. diferric peroxo. This mode of binding oxygen has the remarkable advantage of (1) not featuring a superoxide ligand (unlike Hb), which drastically reduces the reactivity towards NO, and (2) exhibiting stability towards peroxide (unlike Hb).

Anticancer Drugs
Cisplatin and related compounds are known to exert much of their useful therapeutic effects via binding to DNA. The need for more effective drugs as well as the wide range of side-effects (nausea, progressive peripheral sensory neuropathy, fatigue, vomiting, alopecia, hematological suppression, renal damage) have, for several decades now, fueled interest into understanding the complex mechanisms of interaction of cisplatin and related compounds with various biomolecules. One notable observation in this respect has been that platinum can bind to a range of proteins, as demonstrated by elemental analyses, chromatography and mass spectrometry. Our own research, with established as well as with experimental drugs, including natural extracts of various sources, is seeking to investigate the free-radical mechanisms involved in such drug-protein interactions, with purified proteins as well as with intact cells.

Small Molecule Activation at Biological Complexes (high-valent and super-reduced centers; linkage isomerism)
Reduction of nitrite to nitric oxide is essential in certain living species, and has recently been proposed to be an important secondary function of hemoglobin in humans. In vivo, nitrite reduction is accomplished by metalloenzymes, involving direct metal-nitrite coordination. We proposed that linkage nitro/nitrito isomerism is an essential part of the mechanism in copper and in heme d1-containing nitrite reductases. Recent experimental work has also shown involvement of linkage isomerism in catalytic reduction of nitrite by free hemes and related small complexes in solution. This mechanism reconciles the cd1NIR chemistry with the puzzling fact that Fe(III)-NO is kinetically inert and hence cannot possibly be a part of the cd1NIR catalytic cycle.

Proteins such as cytochrome P450 (P450), horseradish peroxidase (HRP), hemoglobin and catalase are all known to bind and/or ruduce (activate) dioxygen at their heme active sites, in the ferrous form. Our interest has been in defining the properties and reactivity of the transient adducts (nature of ferrous-dioxygen bonding, nature of ferric-peroxo interaction, electronic structure and protonation state of ferryl, i.e. Compounds I and II).

We are also pursuing the related reactions of heme systems with sulfide and sulfur oxyanions (e.g., sulfite reductase and sulfhemoglobin chemistry), as well as with halide oxyanions (relevant to myeloperoxidase, chlorite discutase and others). We have more recently extended this line towards other transition metal - containing macrocyclic complexes, such as cobalamin, porphyrazines and phthalocyanines. In such systems, unusual metal oxidation states (e.g., Fe(IV), Fe(I), Fe(0), Co(I)) under physiologically-relevant conditions are a common theme.

Laccase (p-diphenol:dioxygen oxidoreductase), one of the oldest discovered enzymes, contains four copper ions in two active sites and catalyzes a monoelectronic oxidation of substrates such as phenols and their derivatives, or aromatic amines, coupled to a four-electron reduction of dioxygen to water. The catalytic mechanism was studied for decades but is still not completely elucidated, especially in terms of the reduction of dioxygen to water. The high interest in laccases is explained by the large number of biotechnological applications. We have purified and characterized laccase-type enzymes, with interest in their applications as well as in further understanding their mechanisms of action.


Polyoxometalates (POMs) comprise a rich and diverse family of metal-oxygen clusters of the early transition metals in high oxidation states, most commonly V(V), Mo(VI) and W(VI), with unique versatility in terms of shape, polarity, redox potentials, surface charge distribution, acidity, and solubility. We are analyzing iron-substituted POMs in search of features common with/reminiscent of those seen in iron-based redox metalloenzymes.

Molecular Modelling of Biopolymers
We are investigating preferences for various types of secondary structure, and tools for predicting three-dimensional structures in peptides and in other biopolymers, such as polylactic acid and polymers relevant in dental materials.

Natural Extracts
We are examining plant extracts, fungi, food- or drug-related components, or other natural products, for their antioxidant and biological activity (anticancer, etc.), with emphasis on chemical mechanisms of their action.

Cultural Studies
We are also pursuing the application of chemical and biochemical concepts in social/cultural studies.

Vacancies and internships. Join us!
We always welcome students interested in studying and conducting scientific research. The steps below refer to unpaid internships, undergraduate diploma and MSc papers. Paid positions and scholarships are occasionally available (and will be advertised here) – though one should note that they are relatively rare and usually come on a very competitive basis.

1. If possible: talk to somebody already in the group and/or ask people from other groups about what you can expect. Look up the groups web page. Note that membership to the group entails as minimum requirements (1) attendance of weekly group meetings (where you would also have to participate in the discussions, discuss your progress over the past week, and occasionally give presentations), (2) attending, within reasonable limits, the scientific events (conferences, seminars) indicated/recommended in group meetings or in other communications within the group, (3) observe any other rules laid out in the group’s handbook.

2. Schedule a preliminary interview with prof. Radu Silaghi-Dumitrescu – either by stopping by room 80 or by messaging radu.silaghi@ubbcluj.ro

3. Prepare a motivation letter (at least one A4 page, Times New Roman 12, spaced at 1.5) describing your motivations and expectations regarding your research activity within the group, as well as further context (e.g., future plans)

4. Prepare a short essay (not shorter than 2 pages) expressing your opinions (including any possible criticisms) about the relevance and contributions of science (be they good or bad, small or large) in an event/topic of significant public interest – such as the COVID crisis, pollution, globalization, immigration, global warming, deforestation, vaccination, online culture (e.g., online teaching, social media etc), development of medical drugs, or any other topics (they can also be much narrower than the examples given above). Submit the letter and the essay to radu.silaghi@ubbcluj.ro and schedule an interview based on these, where decision on acceptance will be made.

10.09.2022 - Wonderful 18th Central European Symposium on Theoretical Chemistry in Hungary. Invited lecture by prof Silaghi-Dumitrescu - "Spectral simulations for bioinorganic centers: in the eye of the beholder"

22.07.2022 - Our team attended the 16th European Biological Inorganic Chemistry Conference (EuroBIC 16) - with Radu Silaghi-Dumitrescu, Adrian MV Brânzanic, Maria Lehene, Cezara Zagrean-Tuza and Artiom Gaina-Gardiuta - talking about cobalamin, plant globins and sulfite reductases. Great meeting - chapeau to the organizers.

23.04.2022 - Our new paper is out - in Dyes and Pigments. Thanks Bianca Stoean, Luiza Gaina, Luminita Silaghi-Dumitrescu and team for the opportunity to contribute. Interesting case where the absorption and fluorescence spectra of phenothiazines are only correctly predicted, to the detail, not by simple TD-DFT calculations but rather by more complex vibronic considerations. In fact, the vibronic components really are the major contributor both in terms of defining the wavelength and in terms of defining the intensity and shape of the signals. Food for thought! The synthesis, and in vitro effect on human ovarian cancer cells are the main topic of the paper - and quite interesting, too: https://www.sciencedirect.com/science/article/abs/pii/S0143720822003825

01.06.2022 - Sign of the times: rising tide of extreme discourse in (and on) Romanian academia on the topic of plagiarism. Whistleblowers under siege - comment from prof.

The MolMod lectures

The MolMod Lectures are a series of research-informed on-line and/or hybrid tutorials initiated in 2022 and focused on topics related to Molecular Modeling in Chemistry and Biochemistry. This series of lectures is an extension of the homonymous conference series and MSc programme hosted by the Babeș-Bolyai University (UBB) via its Faculty of Chemistry and Chemical Engineering since 2007. The expected target will be the students registered for the MolMod MSc programme at UBB, as well as the general audience typically found at the MolMod conference series.
