Synthesis of cyclic peptides

This invention relates to methods for preparing cyclic peptides and peptidomimetic compounds in solution and bound to solid supports, and to cyclic peptide or peptidomimetic libraries for use in drug screening programs. In particular, the invention relates to a generic strategy for synthesis of cyclic peptides or peptidomimetics that enables the efficient synthesis under mild conditions of a wide variety of desired compounds. Two approaches were evaluated for their improvements in solution and solid phase synthesis of small cyclic peptides: positioning reversible N-amide substituents in the sequence; and applying native ligation chemistry in an intramolecular sense. Systematic investigation of the effects of preorganising peptides prior to cyclisation by using peptide cyclisation auxiliaries, and developing new linkers and peptide cyclisation auxiliaries to aid cyclic peptide synthesis gives surprising improvements in both yields and purity of products compared to the prior art methods. The combination of these technologies provides a powerful generic approach for the solution and solid phase synthesis of small cyclic peptides. The ring contraction and N-amide substitution technology of the invention provide improved methods for the synthesis of cyclic peptides and peptidomimetics. When used in conjunction with linker strategies, this combination provides solid-phase avenues to cyclic peptides and peptidomimetics.

Discrimination method for advanced persistent threat attack

The invention relates to a discrimination method for advanced persistent threat attack. The discrimination method comprises the following steps: collecting an API (Application Program Interface) calling sequence of a terminal sample program system; extracting the API calling short sequence of the terminal sample program system through a MapReduce module, then, calculating the information gain of the short sequence, and screening program behavior characteristics with huge information gain; scanning the API calling sequence of the terminal sample program system again to obtain the behavior characteristics of a terminal sample program; using the behavior characteristics of each sample program as input by a statistical machine learning model module, training the statistical machine learning model module until the classification correction rate of the training sample program by the statistical machine learning model module is above 90%, determining a model parameter, and taking the model parameter as an APT (Advanced Persistent Threat) attack discriminator; collecting the system calling sequence of a target terminal program; and after the API calling sequence of the target program is collected and the behavior characteristics of the target program are extracted, judging whether the target program has attack behaviors. The discrimination method is high in APT attack detection capability and shortens the extraction time of program behavior characteristics.

Television program recording method and system

The invention provides a television program recording method and a television program recording system. The television program recording method comprises the steps of: memorizing programs which a user made requests to watch in the past, and generating a historical playing program list; screening programs with a high playing degree of interest from the historical playing program list, and forming a reserved recording program list; receiving program data streams corresponding to television channels, and processing the program data; and judging whether program update exists in the currently playing program data stream of the television channel when compared with program information fields of the corresponding program in the reserved recording program list, if so, recording the updated program quickly and saving the recorded program in a program database. The television program recording system comprises the program database, a historical memory module, a program screening module, a data receiving module, a program update judgment module and a program updating module. The television program recording method and the television program recording system can automatically reserve program recording according to user watching records, so as to prevent the situation that the program is missed or cannot be watched timely because the program recording cannot be reserved in advance.

Sign language translation method based on BP neural network

The invention discloses a sign language translation method based on a BP neural network. The sign language translation method is characterized by comprising the following steps: 1, acquiring a gesturevoltage signal by utilizing Raspberry Pi 3B through a wearable data glove; 2, compiling sign language words and common sign language sentences corresponding to each group of gesture voltage signals into a sign language sentence library by utilizing a signal screening program; 3, writing a neural network classification program comprising a BP neural network structure framework model, a data transmission module and a storage module, wherein the BP neural network structure framework model adopts a three-layer neural network comprising an input layer, an output layer and a hidden layer; 4, converting the gesture voltage signals received each time into sign language words through a BP neural network framework model; and 5, converting the sign language words obtained in the step 4 into sign language word groups within a period of time, matching the sign language word groups with a sign language statement library, associating and filling into sentences, and outputting a result. According tothe invention, automatic real-time translation identification of sign language is realized by combining a neural network and a sensing technology.
