[0011] Incidentally, the program for realizing the software appearing in this embodiment may be provided as a non-transitory computer-readable medium, or may be provided so that it can be downloaded from an external server, or may be provided so that the program is started on an external computer and its functions are realized on a client terminal (so-called cloud computing).

[0012] In this embodiment, the term "unit" may also include, for example, a combination of hardware resources implemented by a circuit in the broad sense and software information processing that can be specifically realized by these hardware resources. In addition, this embodiment handles various types of information, which may be represented by, for example, physical values ​​of signal values ​​representing voltages and currents, high and low signal values ​​as a binary bit set consisting of 0 or 1, or quantum superposition (so-called quantum bits), and communication and calculations may be performed on a circuit in the broad sense.

[0013] In addition, a circuit in the broad sense is a circuit realized by at least appropriately combining a circuit, circuitry, a processor, a memory, etc. That is, it includes an application specific integrated circuit (ASIC), a programmable logic device (e.g., a simple programmable logic device (SPLD), a complex programmable logic device (CPLD), and a field programmable gate array (FPGA)), etc.

[0014] 1. Hardware Configuration In this section, the hardware configuration of the information processing system etc. according to this embodiment will be described.

[0015] 1.1 Information Processing System 100 FIG. 1 is a configuration diagram showing an information processing system 100 according to this embodiment. The information processing system 100 includes a server 1, a user terminal 2, and a synthesis device 3, which are connected via a network 4. These components will be further described. Here, a system exemplified as the information processing system 100 is one that is made up of one or more devices or components. Therefore, even the server 1 alone or the user terminal 2 alone is an example of a system.

[0016] 1.2 Server 1 2 is a block diagram showing the hardware configuration of server 1. Server 1 has a communication unit 11, a storage unit 12, and a control unit 13, and these components are electrically connected via a communication bus 10 inside server 1. Each component will be further described below.

[0017] The communication unit 11 is preferably a wired communication means such as USB, IEEE1394, Thunderbolt (registered trademark), wired LAN network communication, etc., but may also include wireless LAN network communication, mobile communication such as 3G / LTE / 5G, Bluetooth (registered trademark) communication, etc. as necessary. In other words, it is more preferable to implement it as a collection of multiple communication means. In other words, the server 1 communicates various information with the user terminal 2 via the communication unit 11 and the network 4.

[0018] The memory unit 12 stores various pieces of information defined above. This may be implemented, for example, as a storage device such as a solid state drive (SSD) that stores various programs related to the server 1 executed by the control unit 13, or as a memory such as a random access memory (RAM) that stores temporarily required information (arguments, arrays, etc.) related to program calculations. Alternatively, a combination of these may be used. In particular, the memory unit 12 stores various programs related to the server 1 executed by the control unit 13.

[0019] The control unit 13 processes and controls the overall operations related to the server 1. The control unit 13 is, for example, a central processing unit (CPU) not shown. The control unit 13 realizes various functions related to the server 1 by reading out predetermined programs stored in the storage unit 12. In other words, information processing by software stored in the storage unit 12 is specifically realized by the control unit 13, which is an example of hardware, and can be executed as each functional unit included in the control unit 13. These will be described in more detail in the next section. Note that the control unit 13 is not limited to being single, and multiple control units 13 may be provided for each function. A combination of these may also be used.

[0020] 1.3 User terminal 2 3 is a block diagram showing the hardware configuration of the user terminal 2. The user terminal 2 has a communication unit 21, a storage unit 22, a control unit 23, a display unit 24, and an input unit 25, and these components are electrically connected via a communication bus 20 inside the user terminal 2. The explanation of the communication unit 21, the storage unit 22, and the control unit 23 will be omitted as they are substantially the same as the communication unit 11, the storage unit 12, and the control unit 13 in the server 1 described above.

[0021] The display unit 24 may be included in the housing of the user terminal 2, or may be externally attached. The display unit 24 displays a graphical user interface (GUI) screen that can be operated by the user. This is preferably implemented by using a display device such as a CRT display, a liquid crystal display, an organic EL display, or a plasma display, depending on the type of user terminal 2. Here, the display unit 24 will be described as being included in the housing of the user terminal 2.

[0022] The input unit 25 may be included in the housing of the user terminal 2, or may be externally attached. For example, the input unit 25 may be implemented as a touch panel integrated with the display unit 24. A touch panel allows the user to input tapping, swiping, and the like. Of course, a switch button, a mouse, a QWERTY keyboard, or the like may be used instead of a touch panel. That is, the input unit 25 accepts an operation input made by the user. The input is transferred as a command signal to the control unit 23 via the communication bus 20, and the control unit 23 can execute predetermined control or calculation as necessary.

[0023] 1.4 Synthesizer 3 In this embodiment, the synthesizer 3 is an apparatus that performs chemical conversion based on a predetermined synthesis recipe. Although not shown, the synthesizer 3 may have various components that are included in known synthesizers. Typically, the synthesizer 3 is configured to perform various operations that can be used in chemical synthesis, such as receiving raw materials, adding reactants, heating, stirring, cooling, and adjusting the atmosphere. In this embodiment, the synthesizer 3 is configured to convert a raw material polysaccharide into a modified polysaccharide.

[0024] 2. Functional configuration This section describes the functional configuration of this embodiment. Fig. 4 is a functional block diagram showing the functions of the server 1. As described above, information processing by software (stored in the storage unit 12) is specifically realized by hardware (control unit 13), and can be executed as each functional unit included in the control unit 13.

[0025] Specifically, the server 1 (control unit 13) may include, as its functional units, a reception unit 131, an output unit 132, and a creation unit 133. Note that these functional units may be increased or omitted as appropriate depending on the intended use, etc.

[0026] The receiving unit 131 is configured to be able to execute the receiving step. That is, the receiving unit 131 is configured to acquire various information necessary for information processing. For example, the receiving unit 131 may read out various information stored in advance in the storage unit 12, or may acquire various information from external devices via the network 4 and the communication unit 11. In particular, the receiving unit 131 receives target physical properties of a modified polysaccharide obtained by modifying a polysaccharide. This will be described in further detail later.

[0027] The output unit 132 is configured to execute an output step. That is, the output unit 132 is configured to output various information. The information output by the output unit 132 typically includes visual information, auditory information, and the like. Typically, the output unit 132 is configured to generate various display information and control the display content visible to the user. The display information may be information itself generated in a manner visible to the user, such as a screen, image, icon, text, etc., or may be rendering information for displaying a screen, image, icon, text, etc. on the display unit 24 of the user terminal 2. In particular, the output unit 132 outputs a structure of a modified polysaccharide that satisfies the physical properties based on the received physical properties and preset reference information. Here, the reference information includes information associating a structure obtained by modifying a portion of a polysaccharide containing a hydroxyl group with the physical properties corresponding to the modified structure. This will be described in further detail below.

[0028] The creation unit 133 is configured to be able to execute the creation step. That is, the creation unit 133 creates a synthesis recipe for converting a polysaccharide into a modified polysaccharide based on the structure of the modified polysaccharide output in the output step. This will be described in more detail later.

[0029] 3. Details of data processing In Section 3, an information processing method executed by the information processing system 100 etc. will be described with reference to an activity diagram etc. Fig. 5 is an activity diagram showing the flow of information processing using the information processing system 100 etc.

[0030] <Applicable to> Before describing the details of the information processing, first, an application of the information processing of this embodiment will be described. The information processing of this embodiment involves "polysaccharides" and "modified polysaccharides," where "polysaccharides" refers to compounds having a skeleton formed by condensation of monosaccharides (e.g., glucose). Specific examples of polysaccharides include, but are not limited to, cellulose, starch, and dextrin. Furthermore, polysaccharides typically have hydroxyl groups in their chemical structure.

[0031] The "monosaccharide" may be glucose, as well as ribose, erythrose, xylose, arabinose, mannose, galactose, and other sugars.

[0032] On the other hand, "modified polysaccharides" refer to compounds in which the partial structure of the above-mentioned polysaccharides has been modified. Here, modification typically involves converting a portion containing a hydroxyl group into another chemical structure. The structure in which the hydroxyl group is modified here may be based on a known synthesis method, and as an example, the portion containing a hydroxyl group may be a structure in which the portion is acylated, etherified, silyl etherified, reduced, or oxidized. The "portion containing a hydroxyl group" may be the hydroxyl group itself, or may be a portion containing a hydroxyl group and a carbon atom to which the hydroxyl group is bonded.

[0033] The information processing method of this embodiment can be applied to various polysaccharides, and as an example, the polysaccharide may be cellulose, and the modified polysaccharide may be modified cellulose. Cellulose (modified cellulose) is easily available and can easily exhibit various functions, so it is preferably applied to the information processing method of this embodiment.

[0034] Cellulose and modified cellulose will be explained in more detail based on the following chemical formulas (1) and (2).

[0035] [ka]

[0036] Chemical formula (1) shows the structure of cellulose. That is, cellulose is a compound in which glucose, a monosaccharide, is linked by β-1,4-glycosidic bonds. Note that * in chemical formula (1) represents a bond, and glucose units shown in the formula are linked to other glucose units. Note that the molecular weight of cellulose is not particularly limited, but an example is between 30,000 and 5,000,000.

[0037] [ka]

[0038] Chemical formula (2) is an example of a formula showing the structure of modified cellulose. In the cellulose of chemical formula (1) shown above, hydroxyl groups are bonded to the carbon atoms at the 2nd, 3rd, and 6th positions. However, in the modified cellulose of chemical formula (2), the sites containing these hydroxyl groups can be converted to other structures. That is, in chemical formula (2), R1 may be a group into which the hydroxyl group (-OH) bonded to the carbon atom at the 2nd position in chemical formula (1) is converted; R2 may be a group into which the hydroxyl group (-OH) bonded to the carbon atom at the 3rd position in chemical formula (1) is converted; and R3 may be a group into which the hydroxymethyl group (-CH2OH) containing the carbon atom at the 6th position in chemical formula (1) is converted.

[0039] As described above, the structure in which the hydroxyl groups in the modified polysaccharide (modified cellulose) are modified may be a structure in which the site containing the hydroxyl group is acylated, etherified, silyl etherified, reduced, or oxidized, but more specific examples include the following:

[0040] Examples of the structure in which a site containing a hydroxyl group is acylated include structures in which the hydroxyl group is converted into an acetyl group, a propionyl group, a benzoyl group, or the like.

[0041] Examples of the structure in which a moiety containing a hydroxyl group is etherified include structures in which the hydroxyl group is converted into a methoxy group, an ethoxy group, a phenyloxy group, or the like.

[0042] Examples of the structure in which a moiety containing a hydroxyl group is silyl-etherified include structures in which the hydroxyl group is converted into a trimethylsilyloxy group, a triethylsilyloxy group, a diethylmethylsilyloxy group, or the like.

[0043] Examples of structures in which a site containing a hydroxyl group has been reduced include structures in which the hydroxyl group has been substituted with a hydrogen atom.

[0044] Examples of structures in which a site containing a hydroxyl group is oxidized include structures in which a hydroxymethyl group (-CH2OH) is converted into a formyl group, a carboxy group, or the like.

[0045] The modified polysaccharides may be those in which some of the hydroxyl groups of the starting polysaccharide have been modified, i.e., those in which the hydroxyl groups derived from the starting polysaccharide remain.

[0046] <Details of information processing> Next, the information processing will be described in detail. As shown in FIG. 5, in the information processing method of this embodiment, first, in a receiving step, target physical properties of a modified polysaccharide obtained by modifying a polysaccharide are received (activity A001).

[0047] The receiving step shown as activity A001 can be realized by the receiving unit 131 receiving the target physical property by various methods. Such processing is executed, for example, based on an operation on the user terminal 2. A specific mode of such an operation on the user terminal 2 will be described. FIG. 6 is an example of a display screen displayed on the user terminal 2.

[0048] Display screen D1 shown in FIG. 6 is a screen for the "Modified Cellulose Proposal System," and displays forms 51, 52, and 53 in which the molecular weight, target physical properties ("glass transition temperature" is shown as an example), and numerical ranges can be input. While display screen D1 is configured to accept various properties assuming that the polysaccharide is cellulose, a form in which the type of polysaccharide can be specified may also be provided within display screen D1. Display screen D1 also displays a button 54 labeled "Execute." After inputting the various physical properties, the user viewing display screen D1 can click button 54 to accept the various physical properties.

[0049] The target physical properties are not limited to those shown in FIG. 6 and may be various physical properties related to modified polysaccharides. That is, the physical properties that can be received in the receiving step are not limited to thermal properties such as glass transition temperature, but may also include mechanical properties such as tensile strength and elongation; biodegradability; optical properties such as light transmittance and refractive index; electrical properties such as electrical conductivity; and gas permeability. Furthermore, the receiving step is not limited to receiving only a single physical property, but may also receive multiple physical properties. Furthermore, the receiving step of this embodiment may also receive information other than physical properties, such as the molecular weight and purity of the polysaccharide.

[0050] In this way, when the desired physical properties are received, the output unit 132 of the server 1 outputs, as an output step, the structure of a modified polysaccharide that satisfies the physical properties based on the received physical properties and pre-set reference information (activity A002).

[0051] The output step shown as activity A002 is typically performed by matching the received physical properties with previously referenced reference information, which includes information relating a structure obtained by modifying a hydroxyl group-containing portion of a polysaccharide to the physical properties corresponding to the modified structure.

[0052] More specific examples of reference information are shown below. That is, in one aspect, the reference information of this embodiment may be information (typically a database) that associates the structure of a modified polysaccharide that has already been synthesized with the physical properties of the modified polysaccharide. In another aspect, the reference information may be information (typically a trained model) that predicts the structure of a modified polysaccharide (typically the structure as an unknown compound) from given physical properties based on the structure of a modified polysaccharide that has already been synthesized and the physical properties of the modified polysaccharide.

[0053] The reference information may include, in addition to the structure of the polysaccharide modified at a site containing a hydroxyl group and the physical properties corresponding to the modified structure, information on the substitution rate (degree of substitution) of the hydroxyl group, the position of the modified structure, the molecular weight, etc. The inclusion of such information can improve the accuracy of prediction of modified polysaccharides.

[0054] In this way, from the received physical properties, the structures of one or more modified polysaccharides that satisfy the physical properties can be output.

[0055] The structure of such a modified polysaccharide is output, for example, to the display unit 24 of the user terminal 2. FIG.

[0056] Display screen D2 shown in Figure 7 displays candidate compounds (modified cellulose) and their specific chemical structures as table 61. The example of display screen D2 shows which groups are assigned to R1, R2, and R3 in formula (2) above. Display screen D2 also shows predicted glass transition temperatures (predicted Tg values) associated with each candidate compound. Each of these predicted Tg values, XX31, XX32, and XX33, satisfies the numerical range of form 53 shown in Figure 6.

[0057] In the information processing system 100 of this embodiment, the output unit 132 may be configured to present a plurality of modified polysaccharides satisfying the physical properties in a predetermined order. That is, in FIG. 7, there are a plurality of candidate compounds (modified celluloses) satisfying the predetermined glass transition temperature, and in this case, the output unit 132 may be configured to present the candidate compounds in a predetermined order.

[0058] This predetermined order may be set as appropriate, but one example of the predetermined order is an order based on ease of synthesis. For example, the predetermined order may be configured so that candidate compounds with high ease of synthesis are displayed at the top based on factors such as the small number of steps required to convert the hydroxyl group-containing moiety, the ease of application of the agent and conversion conditions used for the conversion, etc. In the example shown in Figure 7, the modified cellulose shown as "Candidate: 1" is displayed at the top based on the fact that the moieties corresponding to R1 and R2 are identical and that a single step is expected to be sufficient for converting them. Other predetermined orders may also be based on the number of citations in literature (academic papers), the CAS number, the molecular weight of the repeating unit, etc.

[0059] In the information processing method of this embodiment, a creation step may be performed as necessary. That is, as shown as activity A003, the creation unit 133 of the information processing system 100 may create a synthesis recipe for converting a polysaccharide into a modified polysaccharide based on the structure of the modified polysaccharide output in the output step.

[0060] This creation step is executed, for example, by the user pressing button 62 shown in FIG. 7. Using the example of modified cellulose shown as "Candidate: 1," pressing button 62 labeled "Create" creates a synthesis recipe that includes a step of oxidizing the hydroxymethyl group corresponding to R3 and a step of acetylating the hydroxyl groups corresponding to R1 and R2. This synthesis recipe may be displayed on display 24 of user terminal 2, or may be printed on a printed material printed by a printing device (not shown). Alternatively, the synthesis recipe created in the creation step may be a signal that drives a predetermined synthesis device (synthesis device 3).

[0061] That is, the synthesizing device 3 may acquire a synthesis recipe created by the information processing system 100 and convert a polysaccharide into a modified polysaccharide based on the synthesis recipe, thereby enabling efficient synthesis of a candidate compound.

[0062] As described above, the information processing system 100 of this embodiment can efficiently output the structure of the target modified polysaccharide by utilizing the received physical properties and predetermined reference information.

[0063] 4.Other In Section 4, modifications of the information processing system 100 and the like will be described.

[0064] In the above-described embodiment, the server 1 executes various information processes. However, the user terminal 2 may execute various information processes. That is, the information processing system of this embodiment may be an information processing system 200 as shown in FIG. 8. FIG. 8 is a configuration diagram illustrating a modified example of the information processing system. That is, in the information processing system 200 shown in FIG. 8, the user terminal 2 may execute various steps, such as a reception step, an output step, and a creation step, as a standalone computer. Note that these various steps may be realized by the functions of the control unit 23 of the user terminal 2. As in the above-described embodiment, the synthesis device 3 may be controlled by the synthesis recipe created by the control unit 23 of the user terminal 2.

[0065] The above embodiment has been described as a configuration of the information processing system 100, but a program for causing at least one computer to execute each step of the information processing system 100 (information processing system 200) may be provided.
