The first Pd-catalyzed asymmetric allenylic [4+1] cycloaddition was successfully developed. Alternatively, tuning the Pd catalyst switched the reactivity toward an unprecedented [4+3] cycloaddition/cross-coupling. Ligands play a vital role in controlling the reaction pathway, allowing highly selective access to different products from identical substrates. Biological evaluation of the obtained compounds led to the discovery of new antitumor targets. A possible mechanism is proposed, suggesting two interesting catalytic cycles for the cycloaddition with palladium-butadienyls. This study also demonstrated the potential and utility of allenic esters as 1,4-biselectrophiles and C-4 synthons for participating in cycloaddition reactions.

Interaction of cluster anions [{Re(6)Q(8)}X-6](4-/3-) (Q = S or Se; X = Cl, Br or I) with molten pro-ligands – pyrazole (pzH) and 3,5-dimethylpyrazole (3,5-Me(2)pzH) has led to the formation of cationic apically homoleptic cluster complexes [{Re(6)Q(8)}L-6](2+) (L = pzH or 3,5-Me(2)pzH). All new compounds were characterized by a set of physicochemical properties such as X-ray diffraction analyses on crystals and powders, FTIR and NMR spectroscopies.

Four [(NNN)(PdCl)-Cl-(II)]+ complexes [chloride-(2,2 ‘:6 ‘,2 ”-terpyridine)Pd-(II)]Cl (PdL1), [chlorido(2,6-bis(N-pyrazol-2-yl)pyridine)Pd(II)]Cl (PdL2), [chlorido(2,6-bis(3,5-dimethyl-N-pyrazol-2-yl)pyridine)Pd(II)]Cl (PdL3) and [chlorido(2,6-bis(3,5-dimethyl-N-pyrazol-2-ylmethyl)pyridine)Pd(II)]BF4 (PdL4) were synthesized and characterized. The rates of substitution of these Pd(II) complexes with thiourea nucleophiles viz; thiourea (Tu), N,N ‘-dimethylthiourea (Dmtu) and N,N,N ‘,N ‘-tetramethylthiourea (Tmtu) was investigated under pseudo first order conditions as a function of nucleophile concentration [Nu] and temperature using the stopped-flow technique. The observed rate constants vary linearly with [Nu]; k(obs) = k(2)[Nu] and decreased in the order: PdL1 > PdL2 > PdL3 >> PdL4. The lower pi-acceptability of the cis-coordinated N-pyrazol-2-yl groups (which coordinates via pyrazollic-N pi-donor atoms) of the PdL2-4 significantly decelerates the reactivity relative to PdL1. Furthermore, the six-membered chelates having methylene bridge in PdL4 do not allow pi-extension in the ligand and introduces steric hindrance further lowering the reactivity. Trends in DFT calculated data supported the observed reactivity trend. Spectrophotometric titration data of complexes with calf thymus DNA (CT-DNA) and viscosity measurements of the resultant mixtures suggested that associative interactions occur between the complexes and CT-DNA, likely through groove binding with high binding constants (K-b = 10(4) M-1). In vitro MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] cytotoxic activity data showed that PdL1 was the most potent complex against MCF7 breast cancer cells; its IC50 value is lower than that of cisplatin. The results demonstrate how modification of a spectator ligand can be used to slow down the reactivity of Pd(II) complexes. This is of special importance in controlling drug toxicity in both pharmaceutical and biomedical applications.

Background: Transrectal ultrasound-guided prostate biopsy (TRBx) or transperineal Bx (TPBx) are considered alternative approaches for the diagnosis of prostate cancer (PCa). However, urinary tract infection (UTI) or other complications could be more frequent in the TRBx approach. Objective: To determine the complication rate following different antimicrobial prophylaxis (AMP; fosfomycin trometamol [FT] vs beta-lactame or fluorochinolones [FQ]) in patients undergoing TRBx or TPBx. Design, setting, and participants: The analyses were based on prospectivelycollected data of a cohort of patients who underwent TRBx or TPBx for elevated prostate-specific antigen (PSA; >= 4 ng/ml) or clinical suspicion of PCa, between September 2016 and March 2017. Patients received a single dose of 3 g oral FT (group A) or, alternatively, FQ or beta-lactame (group B). Intervention:TRBx versus TPBx. Outcome measurements and statistical analysis: Adjustment variables consisted of age, PSA, biopsy technique (TPBx vs TRBx), and antibiotic prophylaxis (FT vs beta-lactame or FQ) using 1:1 propensity-score matching. Overall, 526 patients were considered, of whom 258 received FT (group A) and the other 258 received beta-lactame or FQ (group B). Results and limitations: Overall complications occurred in 390 (75.58%) and major complications in 67/516 (12.98%). Lower prevalence of UTIs was detected in group A (34.1%) compared with that in group B (43.4%; p = 0.03), while similar rates of haematuria (54.7% vs 55.4%), haemospermia (39.5% vs 33.0%), and acute urinary retention (11.6% vs 9.3%) were detected in groups A and B. We found that group B (odds ratio [OR]: 1.54; p = 0.03), I grade haematuria (OR: 6.17; p < 0.01), and II grade haematuria (OR: 5.13; p < 0.01) were significantly associated with increased risk of UTIs. Conclusions: AMP with fluoroquinoles or beta-lactam antibiotics increased the rate of UTIs, when compared with FT, in patients undergoing TRBx or TPBx. The appearance of haematuria or haemospermia is associated with UTIs, suggesting the possibility of tailoring the strategy for prophylaxis in this category of patients. Patient summary: In this study, comparing complications after transrectal ultrasound-guided prostate biopsy versus transperineal biopsy, prophylaxis with fluoroquinoles or beta-lactam antibiotics increased the rate of urinary tract infections when compared with fosfomycin trometamol, regardless of the type of biopsy approach.

The Pd(ii)-catalyzed activation of Csp(2)-H bond and double alkyne annulation which proceeds via allylic isomerization is reported for the first time. This reaction of antipyrines with alkynes provides an efficient synthetic route for the biologically important spiro-cyclopentadiene pyrazolones. In the presence of Lawesson’s reagent, this Pd(ii)-catalyzed annulation reaction affords another spiro-cyclopentadiene pyrazolone which displays very good fluorescence properties.

I found the field of Chemistry very interesting. Saw the article Specific Organocatalysis in Amidation Reaction of Fatty Acid Methyl Esters with 3-(Dimethylamino)-1-propylamine published in 2021.0.

Comparison of various organic compounds such as glycols, amines and alkanolamines as organocatalysts in amidation of fatty acid methyl esters with 3-(dimethylamino)-1-propylamine was made for the first time. It was experimentally detected that catalysts containing OH-groups (alcohols, glycols, glycerol and aminoalcohols) influence the reaction rate. Moreover, catalytic effect is depending on the catalysts geometry significantly. 1,5-diols (e. g. diethylene glycol and diethanolamine) were found to accelerate the reaction more than other OH-groups containing additives. It was supposed, that this catalytic effect is caused by specific associative interactions between reactants and 1,5-diols, what was confirmed by quantum mechanics calculations. Catalysts concentration effects on the reaction rate were also investigated.
