Abstract: A compound represented by the general Formula (I), wherein hydrogen atoms shown as attached to pyrazole and benzimidazole rings are attached to one of nitrogen atoms of the pyrazole or benzimidazole ring, respectively; R1 represents —X-Q-P, wherein X is absent or represents —CH2—, —C(O)—, or —C(O)NH—(CH2)k—, wherein k is 0, 1 or 2; Q is selected from the group consisting of Q1, Q2, Q3, Q4 and Q5; P is absent or represents straight- or branched-chain C1-C3 alkyl, —(CH2)l—NR2R3, or —(CH2)m—C(O)—NR2R3, wherein l and m independently of each other represent 0, 1 or 2, with the proviso that when B in Q1 represents oxygen atom, then P is absent; and R2 and R3 independently represent C1 or C2 alkyl, or R2 and R3 together with nitrogen atom to which they are both attached form a 6-membered saturated heterocyclic ring, wherein one of carbon atoms can be replaced with oxygen, —NH—or —N(C1-C2)alkyl-; and acid addition salts thereof. The compound can be useful in the treatment of cancer diseases.

Abstract: The present invention relates to the application of double-helical oligonucleotides (siRNA) interfering with the mRNA of gene involved in carcinogenesis, particularly the Wnt1, Wnt2 or Her3 genes. Such oligonucleotides may be modified chemically, used in conjunction with viral and non-viral vectors such as lipid complexes. Such oligonucleotides exhibit unusual anti-proliferative properties against tumour cells and may be used in anti-tumour treatment.

Abstract: The invention relates to a process for the preparation of zaleplon (N-[3(3-cyanopyrazolo[1,5-a]pyrim-idin-7-yl)phenyl]-N-ethyl-accramide) in the reaction of 3-dimethylamino-1-(3-N-ethyl-N-acetylamirnophenyl)-2-propen-1-one with 3-aminopyrazole-4-carbonitrile, which comprises carrying out said reaction in an aqueous solution of formic acid at formic acid concentrations in the range of 20–80% (w/w). Zaleplon is useful as an anxiolytic, a sedactive and a skeletal muscle relaxant.

Abstract: Certain toxic compounds (T) such as, for example, compounds based upon diphtheria toxin, ricin toxin, pseudomonas exotoxin, .alpha.-amanitin, pokeweed antiviral protein (PAP), ribosome inhibiting proteins, especially the ribosome inhibiting proteins of barley, wheat, corn, rye, gelonin and abrin, as well as certain cytotoxic chemicals such as, for example, melphalan and daunomycin can be conjugated to certain analogs of gonadotropin-releasing hormone to form a class of compounds which, when injected into an animal, destroy the gonadotrophs of the animal's anterior pituitary gland. Hence such compounds may be used to sterilize such animals and/or to treat certain sex hormone related diseases.
