Opis:
Taxanes, whose mechanism of action is based on blocking the cells’ division of cells, have been commonly used in the chemotherapy process for over two decades. The indications for the use of taxanes include ovarian cancer, breast cancer, lung cancer, prostate cancer, some of gastrointestinal malignant tumors or Kaposi sarcoma. Currently, chemotherapy based on taxanes, as well as every cytostatic medicine, allows to improve survival outcomes in many patients with diagnosed malignancies, although it also involves the occurrence of adverse effects. These adverse events may be life-threatening or at least they can decline the patient’s quality of life. The main aim of this paper is to feature possible ocular side effects during taxane based chemotherapy. Physicians taking care of patients during chemotherapy based on taxanes, as well as on every other cytostatic medicine, should be aware of these probable ocular complications. An early diagnosis of ophthalmic complications caused by chemotherapy makes it possible to avoid long-lasting adverse effects.

Opis:
Conformational preferences of Ac-ΔAla-NMe2 and Ac-(Z)-ΔPhe-NMe2 were studied and compared with those of their monomethyl counterparts as well as with those of their saturated analogues. X-Ray data and energy calculations revealed a highly conservative conformation of the dehydro dimethylamides, which is located in a high-energy region of the Ramachandran map.

Opis:
The crystal structure of Ac-ΔVal-NMe2 (ΔVal = α,β-dehydrovaline) was determined by X-ray crystallography. The found angles φ = -60° and ψ = 125° correspond exactly to the respective values of the (i + 1)th residue in idealised β-turn II/VIa. Ab initio/DFT studies revealed that the molecule adopts the angle ψ restricted only to about |130°| and very readily attains the angle φ = about -50°. This is in line with its solid-state conformation. Taken together, these data suggest that the ΔVal residue combined with a C-terminal tertiary amide is a good candidate at the (i + 1)th position in a type II/VIa β-turn.

Opis:
2-Deamino-2-methyl-N10-propargyl-5,8-dideazafolic acid (ICI 198583) is a potent inhibitor of thymidylate synthase. Its analogue, Nα-[4-[N-[(3,4-dihydro-2-methyl-4-oxo-6-quinazolinyl)methyl]-N-propargylamino]phenylacetyl]-L-glutamic acid, containing p-aminophenylacetic acid residue substituting p-aminobenzoic acid residue, was synthesized. The new analogue exhibited a moderately potent thymidylate synthase inhibition, of linear mixed type vs. the cofactor, N5,10 -methylenetetrahydrofolate. The Ki value of 0.34 μM, determined with a purified recombinant rat hepatoma enzyme, was about 30-fold higher than that reported for inhibition of thymidylate synthase from mouse leukemia L1210 cells by ICI 198583 (Hughes et al., 1990, J. Med. Chem. 33, 3060). Growth of mouse leukemia L5178Y cells was inhibited by the analogue (IC50 = 1.26 μM) 180-fold weaker than by ICI 198583 (IC50 = 6.9 μM).
